The normal matrix (transpose of the inverse of the upper left 3x3 submatrix of the model matrix) can not be used to transform the tangent and bitangent vectors from object space to world space, because the normal matrix doesn't preserve directions of the tangent and bitangent vectors. The tangent and bitangent vectors can be transformed from object space to world space by the upper left 3x3 submatrix of the model matrix.

Updated tutorial:
New features:
- loading terrain from a height map texture
- displaying terrain map
- faster water rendering
- wireframe disabling
- one 256 x 256, one 512 x 512 and one 1024 x 1024 height map textures included

Be cautious with that 1024 x 1024 height map, without a tree structure the performance is poor even on GTX 780 Ti - 25 / 50 FPS with / without wireframe!

Updated tutorial:
Added support for:
- OpenGL matrices
- blending
- texturing and multitexturing
- vertex and element arrays
- vertex and element buffer objects
- GL_ARB_texture_float, GL_ARB_texture_non_power_of_two
- GL_EXT_framebuffer_object, GL_EXT_texture_array, GL_EXT_texture_filter_anisotropic
- short, int, float and double arrays to byte array conversions

We tested all tutorials on the AMD Radeon HD 5750 GPU with Omega 14.12 drivers installed and we found out that the AMD's GLSL compiler doesn't support the mat2x2(vec4) constructor.

September 14, 2014, 10:51 AM
Updated tutorials:
- Screen space ambient occlusion
- Deferred rendering - Point lights
- Deferred rendering - Antialiasing
- Deferred rendering - Screen space ambient occlusion
- Deferred rendering - Shadow cube mapping
- OpenGL 2.1 game engine
|
|
New features:
- 9x9 SSAO blur filter with edge detection, so pixels on edges in final SSAO image are not blurred
- antialiasing method consisting of an edge detection algorithm and a simple blur filter based on the "GPU Gems 3 - Chapter 19. Deferred Shading in Tabula Rasa" article
