//
// This Loader has been originally written by Saurav Mohapatra. I (Nikolaus Gebhardt)
// modified some minor things and integrated it into Irrlicht 0.9. Thanks a lot
// to Saurav Mohapatra for his work on this and that he gave me his permission to
// add it into Irrlicht.
// I did some changes to Saurav Mohapatra's loader, so I'm writing this down here:
// - Replaced all dependencies to STL and stdio with irr:: methods/constructs.
// - Moved everything into namespace irr::scene
// - Replaced logging with Irrlicht's internal logger.
// - Removed dependency to IrrlichtDevice
// - Moved all internal structures into CCSMLoader.cpp
// - Made the texture root parameter dependent on a ISceneManager string parameter
// - removed exceptions
// - Implemented CCCSMLoader as IMeshLoader
// - Fixed some problems with memory leaks
// - Fixed bounding box calculation
//
// The original readme of this file looks like this:
//
// This component provides a loader for the Cartography shop 4.x .csm maps for Irrlicht Engine.
// This is a part of the M_TRIX Project.
// This is licensed under the ZLib/LibPNG license
// The IrrCSM library is written by Saurav Mohapatra.
//
// Features
//
// The IrrCSM library features the following capabilities
//
// * Loads the .csm 4.0 and 4.1 files transparently
// * Presents the loaded file as irr::scene::IAnimatedMesh for easy creation of IOctreeSceneNode
// * Loads the textures given the correct texture root. hence map and textures can be in separate directories
//

compressed separately. The RLE compression is the same compres-sion
algorithm used by the Macintosh ROM routine PackBits, and
the TIFF standard.
If the Layer's Size, and therefore the data, is odd, a pad byte will
be inserted at the end of the row.
*/
/*
A pseudo code fragment to unpack might look like this:
Loop until you get the number of unpacked bytes you are expecting:
Read the next source byte into n.
If n is between 0 and 127 inclusive, copy the next n+1 bytes literally.
Else if n is between -127 and -1 inclusive, copy the next byte -n+1
times.
Else if n is -128, noop.
Endloop
In the inverse routine, it is best to encode a 2-byte repeat run as a replicate run
except when preceded and followed by a literal run. In that case, it is best to merge
the three runs into one literal run. Always encode 3-byte repeats as replicate runs.
That is the essence of the algorithm. Here are some additional rules:
- Pack each row separately. Do not compress across row boundaries.
- The number of uncompressed bytes per row is defined to be (ImageWidth + 7)
/ 8. If the uncompressed bitmap is required to have an even number of bytes per
row, decompress into word-aligned buffers.
- If a run is larger than 128 bytes, encode the remainder of the run as one or more
additional replicate runs.
When PackBits data is decompressed, the result should be interpreted as per com-pression
type 1 (no compression).

Author: Gary Conway (Viper) - co-author of the ZIP file format, Feb 1989,
see the story at http://www.idcnet.us/ziphistory.html
Website: http://idcnet.us
Email: codeslinger@vipergc.com
Created: March 1, 2009
Version: 1.0
Updated:
This module will load SGI .rgb files (along with the other extensions). The module complies
with version 1.0 of the SGI Image File Format by Paul Haeberli of Silicon Graphics Computer Systems
The module handles BW, RGB and RGBA images.
RGB images are stored with either 8 bits per COLOR VALUE, one each for red,green,blue (24bpp)
or 16 bits per COLOR VALUE, again one each for red,green,blue (48 bpp), not including the alpha channel
OPTIONS NOT SUPPORTED
1. 16 bit COLOR VALUES (48bpp modes)
2. COLORMAP = DITHERED mode
For non- run length encoded files, this is the structure
The Header
The Image Data
If the image is run length encoded, this is the structure:
The Header
The Offset Tables
The Image Data
The Header consists of the following:
Size | Type | Name | Description
2 bytes | short | MAGIC | IRIS image file magic number
1 byte | char | STORAGE | Storage format
1 byte | char | BPC | Number of bytes per pixel channel
2 bytes | ushort | DIMENSION | Number of dimensions
2 bytes | ushort | XSIZE | X size in pixels
2 bytes | ushort | YSIZE | Y size in pixels
2 bytes | ushort | ZSIZE | Number of channels
4 bytes | long | PIXMIN | Minimum pixel value
4 bytes | long | PIXMAX | Maximum pixel value
4 bytes | char | DUMMY | Ignored
80 bytes | char | IMAGENAME | Image name
4 bytes | long | COLORMAP | Colormap ID
404 bytes | char | DUMMY | Ignored
Here is a description of each field in the image file Header:
MAGIC - This is the decimal value 474 saved as a short. This identifies the file as an SGI image file.
STORAGE - specifies whether the image is stored using run length encoding (RLE) or not (VERBATIM).
If RLE is used, the value of this byte will be 1. Otherwise the value of this byte will
be 0. The only allowed values for this field are 0 or 1.
BPC - describes the precision that is used to store each channel of an image. This is the number of
bytes per pixel component. The majority of SGI image files use 1 byte per pixel component,
giving 256 levels. Some SGI image files use 2 bytes per component. The only allowed values
for this field are 1 or 2.
DIMENSION - described the number of dimensions in the data stored in the image file.
The only allowed values are 1, 2, or 3. If this value is 1, the image file
consists of only 1 channel and only 1 scanline (row). The length of this
scanline is given by the value of XSIZE below. If this value is 2, the file
consists of a single channel with a number of scanlines. The width and height
of the image are given by the values of XSIZE and YSIZE below.
If this value is 3, the file consists of a number of channels.
The width and height of the image are given by the values of XSIZE and YSIZE below.
The number of channels is given by the value of ZSIZE below.
XSIZE - The width of the image in pixels
YSIZE - The height of the image in pixels
ZSIZE - The number of channels in the image. B/W (greyscale) images are stored as 2 dimensional
images with a ZSIZE of 1. RGB color images are stored as 3 dimensional images with a
ZSIZE of 3. An RGB image with an ALPHA channel is stored as a 3 dimensional image with
a ZSIZE of 4. There are no inherent limitations in the SGI image file format that would
preclude the creation of image files with more than 4 channels.
PINMIN - The minimum pixel value in the image. The value of 0 may be used if no pixel has a value
that is smaller than 0.
PINMAX - The maximum pixel value in the image. The value of 255 may be used if no pixel has a
value that is greater than 255. This is the value that is considered to be full
brightness in the image.
DUMMY - This 4 bytes of data should be set to 0.
IMAGENAME - An null terminated ascii string of up to 79 characters terminated by a null may be
included here. This is not commonly used.
COLORMAP - This controls how the pixel values in the file should be interpreted. It can have one
of these four values:
0: NORMAL - The data in the channels represent B/W values for images with 1 channel, RGB values
for images with 3 channels, and RGBA values for images with 4 channels. Almost all
the SGI image files are of this type.
1: DITHERED - The image will have only 1 channel of data. For each pixel, RGB data is packed
into one 8 bit value. 3 bits are used for red and green, while blue uses 2 bits.
Red data is found in bits[2..0], green data in bits[5..3], and blue data in
bits[7..6]. This format is obsolete.
2: SCREEN - The image will have only 1 channel of data. This format was used to store
color-indexed pixels. To convert the pixel values into RGB values a colormap
must be used. The appropriate color map varies from image to image. This format is obsolete.
3: COLORMAP - The image is used to store a color map from an SGI machine. In this case the
image is not displayable in the conventional sense.
DUMMY - This 404 bytes of data should be set to 0. This makes the Header exactly 512 bytes.

ZSIZE Description
1 BW (grayscale) image
3 RGB image
4 RGBa image with one alpha channel
When the Alpha channel is present, I am not sure with RGB files if
it's a precomputed RGB color or it needs to be completely calculated. My guess
would be that it's not precomputed for two reasons.
1. the loss of precision when calculating the fraction, then storing the result as an int
2. the loss of the original color data when the image might be composited with another. Yes
the original color data could be computed, however, not without another loss in precision
Also, I don't know where to find the background color
Pixmin and Pixmax are apparently the min and max alpha blend values (0-100%)
Complete Alpha blending computation
The actual resulting merged color is computed this way:
(image color ◊ alpha) + (background color ◊ (100% - alpha)).
Using precomputed blending
(image color) + (background color ◊ (100% - alpha)).
Alternatively, the RGB files could use another blending technique entirely

/*
If the image is stored using run length encoding, offset tables follow the Header that
describe what the file offsets are to the RLE for each scanline. This information only
applies if the value for STORAGE above is 1.
Size | Type | Name | Description
tablen longs | long | STARTTAB | Start table
tablen longs | long | LENGTHTAB | Length table
One entry in each table is needed for each scanline of RLE data. The total number of scanlines in the image (tablen) is determined by the product of the YSIZE and ZSIZE. There are two tables of longs that are written. Each consists of tablen longs of data. The first table has the file offsets to the RLE data for each scanline in the image. In a file with more than 1 channel (ZSIZE > 1) this table first has all the offsets for the scanlines in the first channel, followed be offsets for the scanlines in the second channel, etc. The second table has the RLE data length for each scanline in the image. In a file with more than 1 channel (ZSIZE > 1) this table first has all the RLE data lengths for the scanlines in the first channel, followed be RLE data lengths for the scanlines in the second channel, etc.
To find the the file offset, and the number of bytes in the RLE data for a particular scanline, these
two arrays may be read in and indexed as follows:
To read in the tables:
unsigned long *starttab, *lengthtab;
tablen = YSIZE*ZSIZE*sizeof(long);
starttab = (unsigned long *)mymalloc(tablen);
lengthtab = (unsigned long *)mymalloc(tablen);
fseek(rgb->inf,512,SEEK_SET);
readlongtab(rgb->inf,starttab);
readlongtab(rgb->inf,lengthtab);
To find the file offset and RLE data length for a scanline:
rowno is an integer in the range 0 to YSIZE-1 channo is an integer in the range 0 to ZSIZE-1
rleoffset = starttab[rowno+channo*YSIZE]
rlelength = lengthtab[rowno+channo*YSIZE]
It is possible for two identical rows (scanlines) to share compressed data. A completely
white image could be written as a single compressed row and having all table entries point
to that row. Another little hack that should work is if you are writing out a RGB RLE file,
and a particular scanline is achromatic (greyscale), you could just make the r, g and b rows
point to the same data!!
RETURNS: on success true, else returns false

This information only applies if the value for STORAGE is 1. If the image is
stored using run length encoding, the image data follows the offset/length tables.
The RLE data is not in any particular order. The offset tables are used to
locate the rle data for any scanline.
The RLE data must be read in from the file and expanded into pixel data in the following manner:
If BPC is 1, then there is one byte per pixel. In this case the RLE data should be
read into an array of chars. To expand data, the low order seven bits of the first
byte: bits[6..0] are used to form a count. If the high order bit of the first byte
is 1: bit[7], then the count is used to specify how many bytes to copy from the RLE
data buffer to the destination. Otherwise, if the high order bit of the first byte
is 0: bit[7], then the count is used to specify how many times to repeat the value
of the following byte, in the destination. This process continues until a count
of 0 is found. This should decompress exactly XSIZE pixels.
One entry in each table is needed for each scanline of RLE data. The total number of
scanlines in the image (tablen) is determined by the product of the YSIZE and ZSIZE.
There are two tables of longs that are written. Each consists of tablen longs of data.
The first table has the file offsets to the RLE data for each scanline in the image. In

CLMTSMeshFileLoader.cpp
LMTSMeshFileLoader
Written by Jonas Petersen (a.k.a. jox)
Version 1.5 - 15 March 2005
Get the latest version here: http://development.mindfloaters.de/
This class allows loading meshes with lightmaps (*.lmts + *.tga files) that were created
using Pulsar LMTools by Lord Trancos (http://www.geocities.com/dxlab/index_en.html)
Notes:
- This version does not support user data in the *.lmts files, but still loads those files (by skipping the extra data).
License:
--------
It's free. You are encouraged to give me credit if you use it in your software.
Version History:
----------------
Version 1.5 - 15 March 2005
- Did a better cleanup. No memory leaks in case of an loading error.
- Added "#include <stdio.h>" for sprintf.
Version 1.4 - 12 March 2005
- Fixed bug in texture and subset loading code that would possibly cause crash.
- Fixed memory cleanup to avoid leak when loading more then one mesh
- Used the irrlicht Logger instead of cerr to output warnings and errors.
For this I had to change the constructor
from:
CLMTSMeshFileLoader(io::IFileSystem* fs, video::IVideoDriver* driver)
to:
CLMTSMeshFileLoader(IrrlichtDevice* device)
Version 1.3 - 15 February 2005
- Fixed bug that prevented loading more than one different lmts files.
- Removed unnecessary "#include <os.h>".
- Added "std::" in front of "cerr". This was necessary for Visual Studio .NET,
I hope it's not disturbing other compilers.
- Added warning message when a texture can not be loaded.
- Changed the documentation a bit (minor).
Version 1.2
- To avoid confusion I skipped version 1.2 because the website was offering
version 1.2 even though it was only version 1.1. Sorry about that.
Version 1.1 - 29 July 2004
- Added setTexturePath() function
- Minor improvements
Version 1.0 - 29 July 2004
- Initial release

// - removed setTexturePath() and replaced with the ISceneManager::getStringParameter()-stuff.
// - added EAMT_LMTS enumeration value

// This file is part of the "Irrlicht Engine".

//
// This file was originally written by ZDimitor.
// I (Nikolaus Gebhardt) did some few changes to this:
// - replaced logging calls to their os:: counterparts
// - removed some logging calls
// - removed setTexture path and replaced it with the directory of the mesh
// - added EAMT_MY3D file type
// - fixed a memory leak when decompressing RLE data.
// - cleaned multi character constant problems with gcc
// - removed octree child scene node generation because irrlicht is now able to draw
// scene nodes with transparent and sold materials in them at the same time. (see changes.txt)
// Thanks a lot to ZDimitor for his work on this and that he gave me
// his permission to add it into Irrlicht.
