Introduction
This is a translation of Tom's Glass demo from Pascal code to C++ code using
GLUT. The original code used ARBvp1.0 and ARBfp1.0 and some nVidia extensions.
This one uses non-extended ARBvp1.0 and ARBfp1.0 and also GLSL 1.00 (to compare performance)
It uses FBO for Render_To_Texture instead of p-buffer.
This program requires GL 2.0 at least.
The extensions needed are :
- GL_ARB_vertex_program
- GL_ARB_fragment_program
- GL_EXT_framebuffer_object
The Source
The files included are :
- glass_delphi3d.cpp (The main CPP file)
- glass_delphi3d.h (The main H file, with GL entry point declarations)
- global.h (Some type declaractions)
- MemoryManagement.h (Memory management functions used by the OBJ loader)
- TOBJFile.cpp and TOBJFile.h(My OBJ loader class)
- StringFunctions.h (Some string functions used my OBJ loader)
- nv_tga.cpp and nv_tga.h (Nvidia tga loader)
- v_glass.txt f_glass.txt (ARBvp1.0 and ARBfp1.0 for glass effect)
- v_depthmap.txt f_depthmap.txt (ARBvp1.0 and ARBfp1.0 for writing depth to float Render_To_Texture)
- glass_delphi3d.vert glass_delphi3d.frag (GLSL 1.00 version of above)
- depthmap_delphi3d.vert depthmap_delphi3d.frag (GLSL 1.00 version of above)
