Irrlicht Engine

I would like to experiment with shaders and irrlicht to explore the world of shadow mapping, deferred shading, bloom, HDR and other modern rendering techniques. However, I don't really know what GLSL version to commit to writing these shaders in. Here is my criteria for choosing a GLSL version, in d...

Do you know how to search the developer reference? You can just use the search bar to llook up anisotropic and trilinear. Then look for enums and setter functions that apply those enumerated. Let me know if you cNt find it and I'll look it up for you

when you make the texture, you can set up trilinear filtering, and set up a lod bias. try experimeting with those two things.

Play around with the Irrb and blender for your levels. I strongly recommend it. You can bake lighting with blender so you will have very good looking levels. Blender+irrb also supports normal maps on levels and other things that quake 3 does not.

Try out the included 2d graphics tutorial if you have not yet. There is a animation example.

Irrlicht should be able to load the bsp directly. Try the tutorial here: http://irrlicht.sourceforge.net/forum/viewtopic.php?t=40201 you will have to do a lot of tools setup if you use netradient while Irrb and blender work with irrlicht "out of the box." And it does global illumination , ...

Here's a demo if you're interested:

I've gone back to my old project and I got my FPS back up to around 1750 fps using this patch. 1750fps gets me a screen full of text, 4x anisotropic filtering, trilinear filtering, and mipmap generation on every frame. I had to start using the trunk version of Irrlicht, because the 1.8.1 version of ...

Irrlicht already has a ITexture::regenerateMipMapLevels() function, which uses the glGenerateMipmap() function to use the graphics card to rebuild the texture pyramid. I changed how render textures were configured, so that when regnereateMipMapLevels() is called, mip-mapped render textures can filte...

Did you mean "Entities"? Irrlicht does not have an entity system, so you will need to an entity management system yourself. I think a good "state of the art" entity system is the "component based entity system" which you can read about here: http://cowboyprogramming.com...

But, but, but your RTT is so small that you could render to a texture twice as large (2 X 2) and downsample in the shader. I think four texture reads p My rtt dimensions are 1024*768, which is equal to the window size in my test case. When I scale the window, the render texture dimensions also chan...

Adding trillinear filtering knocks me down even more fps, but fixes the mipmap transitions and makes things even more readable - I'll use this from now on, thanks.

Every frame, I am drawing a CEGUI multi-line text box to the render texture. It's a stdout from an interpreter, running in a separate thread. If you're running a fast loop with a print statement every iteration, the screen should theoretically get updated every frame, even at 2000 fps. But you're ri...

Thanks hendu, you're the man. I appreciate your support. Your suggestion is 100% functional, and this setup does effectively generate the mipmaps for the rendertexture. I'm running this in OPENGL, and my textures are 1048*768 (the size of the window) in the ECF_R5G6B5 16bit color mode (the lowest da...

After a bit more searching, I found this thread: http://irrlicht.sourceforge.net/forum/viewtopic.php?f=4&t=48572&hilit=texture+lock&start=45 It looks like RTTs don't have mipmaps. Can someone help me with code to copy data from one ITexture into another? I've seen a few other snippets bu...
