An overview of bump mapping techniques using the OpenGL API
Categories: Developers |
Jul 07, 2004
Bump mapping is a lighting technique that perturbs the normal vector of a surface on a per-pixel basis, using a texture map as input to model the perturbations. By using the perturbed normal for the lighting calculations, the apparent detail of the surface is greatly enhanced, without having to add extra geometric detail to the mesh. This article on bumpmapping discusses the original technique as developed by Jim Blinn, as well as several realtime implementations. The article also provides links to additional background information, useful tools, and implementations of the various techniques using the OpenGL API. The goal of this article is to introduce novice bump mappers to the most important realtime techniques, to explain the buzzwords that surround realtime bump mapping, and maybe also to dispell a myth or two.
Free download of texture mapping chapter from The OpenGL Programming Guide 4th Edition
Categories: Developers |
Jul 07, 2004
Addison-Wesley has provided OpenGL.org with a sample chapter from The OpenGL Programming Guide 4th Edition (Redbook) for download (1.2MB PDF). This is the must-have book for every OpenGL programmer. The sample Chapter 9 covers texturing mapping. After reading this chapter you should be able to:
- Specify texture images in compressed and uncompressed formats
- Control how a texture image is filtered as it’s applied to a fragment
- Create and manage texture images in texture objects and, if available, control a high-performance working set of those texture objects
- Specify how the color values in the image combine with those of the fragment to which it’s being applied
- Supply texture coordinates to indicate how the texture image should be aligned with the objects in your scene
- Generate texture coordinates automatically to produce effects such as contour maps and environment maps
- Perform complex texture operations in a single pass with multitexturing (sequential texture units)
- Use texture combiner functions to mathematically operate on texture, fragment, and constant color values
- After texturing, process fragments with secondary colors
- Perform transformations on texture coordinates using the texture matrix
- Render shadowed objects, using depth textures
Crystal Space: 0.98r002 enhances speed and support for OpenGL Shaders
Categories: Developers |
Jul 07, 2004
Crystal Space is an Open Source 3D Engine that uses the OpenGL API on Linux, Windows, and MacOS/X. v0.98r002 has much better support for advanced OpenGL features (shaders, vertex and fragment programs, stencil shadows, etc). In general Crystal Space has become faster and more mature. One important thing in this release is that the new renderer architecture is much more usable. It is still not enabled as default because some important parts are still missing but if you only need OpenGL and don’t depend on volumetric fog then it is strongly recommend to use the new renderer architecture. Other features include support for cal3d models (skeletal animation), a new terrain engine that supports splatting (combining multiple textures dynamically) and scattering, and updated and enhanced documentation.
