Function Documentation

shader_t* shader_create (    )

This creates a new empty shader. Shaders created with the shader_create* functions will be automatically deleted on shutdown. Definition at line 269 of file r_shader.cpp. Referenced by shader_load().

shader_t* shader_create_simple (  ushort    blendtype, sshort    texture )

This creates a shader with 1 stage, the given texture and blendtype. See shader_init for details. Shaders created with the shader_create* functions will be automatically deleted on shutdown. Definition at line 229 of file r_shader.cpp. References shader_init(). Referenced by shader_load().

float shader_get_waveform_frac (  const shader_waveform_t *    wf )

get waveform amplitude Gets the current amplitude for a shader wave form between 0 and 1. Definition at line 190 of file r_shader.cpp. References PI2. Referenced by renderer_c::render_verts().

void shader_init (  shader_t *    shader, ushort    blendtype, sshort    texture )

Initializes a shader. It will have one shaderstage with the following properties: shader->dynamic = 0; shader->passes[n].scalex = 1; shader->passes[n].scaley = 1; shader->passes[n].soffsetx = shader->passes[n].soffsety = shader->passes[n].offsetx = shader->passes[n].offsety = 0; shader->passes[n].magfilter = TF_LINEAR; shader->passes[n].minfilter = TF_LINEAR; shader->passes[n].texwrapu = shader->passes[n].texwrapv = TW_REPEAT; shader->passes[n].rotation = shader->passes[n].scrollx = shader->passes[n].scrolly = 0.0f; shader->passes[n].shiny = 0; shader->passes[n].colorwave.type = 0; shader->passes[n].colorwave.bias = 1; shader->passes[n].color1 = shader->passes[n].color2 = 0xFFFFFFFF; shader->passes[n].scalewavex.type = 0; shader->passes[n].scalewavex.bias = 1; shader->passes[n].scalewavey.type = 0; shader->passes[n].scalewavey.bias = 1; shader->passes[n].lightmap = 1; shader->passes[n].blendtype = BT_OPAQUE; shader->passes[n].twosided = 0; shader->passes[n].nodepth = 0; shader->passes[0].blendtype = blendtype; shader->passes[0].texture = texture; Definition at line 247 of file r_shader.cpp. References shader_initstage(). Referenced by shader_create_simple().

void shader_initstage (  shader_t *    shad, ushort    n )

This initializes a shader stage. See shader_init for details. Definition at line 138 of file r_shader.cpp. Referenced by shader_init(), and shader_load().

shader_t* shader_load (  const char *    fname )
