Irrlicht Engine

You are right, nvidia drivers don't have "ANGLE_texture_compression_dxt". I thought ANGLE needs only "EXT_texture_compression_dxt1" to support DXT textures. That's sad
Thank you very much!

Thank you, very much! That's exactly what was wrong.
I definitely will learn to use debugger.

I try to load DXT texture w/ Irrlicht 1.9 (GLES2 backend, Google ANGLE as emulator), but get error from Irrlicht: "DXT texture compression not available." My desktop driver definitely supports DXT1 compression. As far as I know ANGLE also supports it. What is wrong? Is it possible to load compressed ...

What do you mean? dataSize is local variable - initially it can be any value (not only 0). If you know what is wrong, please, could you point it out.

I try to implement KTX loader for Irrlicht. The implementation is limited: only supported format is ECF_ETC1 + loaded KTX must contain mipmaps.
Here is my code (please, note that i'm just beginning c++ programming :wink: ).

//CImageLoaderKTX.h

#ifndef __C_IMAGE_LOADER_KTX_H_INCLUDED__
#define __C ...

Thank you, very much! That's exactly what was wrong.

This doesn't look like a current version (include for IContextManager isn't in line 12 but line 20 in current svn ogl branch).
I just removed all comments from source files (easier to read). Anyway, please, can you say (based on this gcc output) what file I should edit/explore to find the problem ...

I try to compile CEGLManager.cpp w/ MinGW and get this error:

In file included from CEGLManager.h:12:0,
from CEGLManager.cpp:1:
../include/IContextManager.h:10:3: error: expected class-name before '{' token
make: *** [gles2/CEGLManager.o] Error 1

Seems like sort of circular includes/references ...

Hi,

I'm trying to use Irrb but I can't make it work in Blender 2.62.

I downloaded the latest SVN version and copied the scripts to Blender scripts/addons directory.
I can activate the import-export Addon in Blender User Preferences, but when I select some meshes and I go to export, I got no ...

Thank you, very much!
I didn't know because read only documentation/comments inside source files.

I need to draw line in 3d (white line on black background). I use OpenGL driver. Similar function that draws 2d line works great, but draw3DLine doesn't work.

while(device->run())
{
driver->beginScene(true, true, video::SColor(255,0,0,0));
driver->draw3DLine(core::vector3df(0, 0, 0), core ...

Yes, I already use it, but this seems to be the most straightforward approach.

draw2DImage() in COpenGLDriver class will render image relative to screen coordinates (so even if camera moves the image will kind of move with it). I want the image to be rendered only at it's specific position (call it absolute position) - so when camera moves the image will scroll out and then ...

Actually, it has signature: That changes everything - mipmapData is the default parameter, we can pass 0.

I try to load GLES1 texture from file.
In CNullDriver.cpp I found this:

texture = createDeviceDependentTexture(image, hashName.size() ? hashName : file->getFileName() );

createDeviceDependentTexture() must take 3 parameters, but I see only 2. It has signature

ITexture* CNullDriver ...
