Arauna Ray Tracer

Be the first to comment - What do you think?  Posted by JeGX - at 09:29

Categories: Programming   Tags: , , , , ,

Arauna is a real-time ray tracer developed for game development. Being a real-time ray tracer, it is experimental, and does not yet deliver the performance needed to produce graphics of the same quality as modern games do using a GPU. However, in its class, it is one of the fastest (probably the fastest) renderer. Two games have been developed already using Arauna, both by students of the IGAD program of the NHTV University of Applied Sciences (Breda, The Netherlands).

DirectX 11 to be discussed in just weeks!

Be the first to comment - What do you think?  Posted by JeGX - 2008/07/10 at 10:38

Categories: Microsoft DirectX, Programming   Tags: , , , , , , ,

Microsoft will start talking about DirectX 11 in less than two weeks. his conference takes place on the 22 and 23 July in Seattle, Washington.

The big feature of DirectX 11 is tessellation / displacement while we also heard that multithreaded rendering and compute shaders are part of it. DirectX 11 also brings shader model 5.0 but we don’t know many details about it.

It looks like DirectX 11 will stick to rasterization as there is no any mentioning of Ray tracing support.

Modernizing the Quake2 renderer

Be the first to comment - What do you think?  Posted by JeGX - 2008/06/25 at 10:06

Categories: 3D Engines, OpenGL, Programming   Tags: , , , , ,

Jay Dolan recently blogged about some of the performance optimizations he made to his Quake2-based engine, Quake2World. He provides links to various points in the source code to give context around some of the topics he discusses.

Read the post HERE.

Quake2 was released in 1997. Hardware acceleration was only available on higher-end PC’s, and things like multitexture and vertex arrays which are commonplace today didn’t even exist then. So naturally, Quake2′s rendering techniques appear very dated in 2008. Multitexture was made a part of the OpenGL specification in version 1.2.1, and is available on most 2nd generation hardware (TNT or newer). I strongly recommend cleaning up the renderer and removing any non-multitexture rendering paths.

Texture binds (glBindTexture) are rather expensive too, and so to minimize these per frame, you should group the world surfaces by texture before iterating over them. Note that a simple grouping operation is significantly cheaper than a qsort — overall order is not important, we just want to minimize texture changes.

OpenGL demos taking advantage of Shader Model 4

Be the first to comment - What do you think?  Posted by JeGX - 2008/06/23 at 10:04

Categories: OpenGL, Programming   Tags: , , , ,

Naixela released two demos “geometry shader painterly rendering” and “geometry shader tessellation” taking advantage of Shader Model 4 (inclusive source code).

- Geometry Shader Painterly Rendering Demo
Renders a scene into color, position, and normal textures, and then outputs the scene as a large number of brush strokes covering the screen using the geometry shader.

- Geometry Shader Tessellation Demo
Tessellates a heightfield based on distance to the viewer using the geometry shader.
