get_alpha_cutoff_shader()

virtual shader_ptr_type gdk::graphics::context::get_alpha_cutoff_shader ( ) const

nodiscardpure virtual

Basic unlit forward renderer program: Attributes:

• vec3 pos
• vec2 uv Uniforms:
• _MVP: model-view-projection matrix
• _Texture: used to color frags Vertex shader behavior:
• multiply position by mvp Fragment shader behavior:
• sample _Texture, if alpha is 0, discard frag, otherwise write frag to color buffer

Implemented in gdk::webgl1es2_context.
