Robert Bragg 353ea5299b cogl-shader: Prepend boilerplate for portable shaders ... We now prepend a set of defines to any given GLSL shader so that we can define builtin uniforms/attributes within the "cogl" namespace that we can use to provide compatibility across a range of the earlier versions of GLSL. This updates test-cogl-shader-glsl.c and test-shader.c so they no longer needs to special case GLES vs GL when splicing together its shaders as well as the blur, colorize and desaturate effects. To get a feel for the new, portable uniform/attribute names here are the defines for OpenGL vertex shaders: #define cogl_position_in gl_Vertex #define cogl_color_in gl_Color #define cogl_tex_coord_in gl_MultiTexCoord0 #define cogl_tex_coord0_in gl_MultiTexCoord0 #define cogl_tex_coord1_in gl_MultiTexCoord1 #define cogl_tex_coord2_in gl_MultiTexCoord2 #define cogl_tex_coord3_in gl_MultiTexCoord3 #define cogl_tex_coord4_in gl_MultiTexCoord4 #define cogl_tex_coord5_in gl_MultiTexCoord5 #define cogl_tex_coord6_in gl_MultiTexCoord6 #define cogl_tex_coord7_in gl_MultiTexCoord7 #define cogl_normal_in gl_Normal #define cogl_position_out gl_Position #define cogl_point_size_out gl_PointSize #define cogl_color_out gl_FrontColor #define cogl_tex_coord_out gl_TexCoord #define cogl_modelview_matrix gl_ModelViewMatrix #define cogl_modelview_projection_matrix gl_ModelViewProjectionMatrix #define cogl_projection_matrix gl_ProjectionMatrix #define cogl_texture_matrix gl_TextureMatrix And for fragment shaders we have: #define cogl_color_in gl_Color #define cogl_tex_coord_in gl_TexCoord #define cogl_color_out gl_FragColor #define cogl_depth_out gl_FragDepth #define cogl_front_facing gl_FrontFacing		2010-11-10 14:24:52 +00:00
