Member Function Documentation

get_alpha_cutoff_shader()

virtual graphics::context::built_in_shader_ptr_type gdk::webgl1es2_context::get_alpha_cutoff_shader ( ) const

overridevirtual

A forward renderer shader program with the following properties:

• required attributes: vec3 pos, vec2 uv
• vertex shader: mvp mul only
• fragment shader: colors frags with 2d sampler named "_Texture"
• If alpha channel is < 1.0, the fragment is discarded

Implements gdk::graphics::context.

get_pink_shader_of_death()

virtual built_in_shader_ptr_type gdk::webgl1es2_context::get_pink_shader_of_death ( ) const

overridevirtual

A forward renderer shader program useful for displaying render errors:

• required attributes: vec3 pos
• vertex shader: mvp mul
• fragment shader: all frags are colored neon pink

Implements gdk::graphics::context.
