The parameters to create a ShaderProgram

Fields

vertex_input: &'a [Attribute]

The inputs to the vertex shader stage, which are also the inputs to the whole shader

fragment_input: &'a [Attribute]

The inputs to the fragment shader stage, which are also the outputs from the vertex shader

uniforms: &'a [Uniform]

The uniform values available to all shader stages, across all vertices of a draw call

Uniforms can be bound with ShaderProgram::set_uniform

vertex_shader: &'a str

The text of the vertex shader stage

Do not include the vertex inputs, outputs, or uniforms, use the vertex_input, fragment_input, and uniforms fields instead. The inputs to this stage are defined as the vertex_input and the ouptuts are the fragment_input as well as gl_Position, a vec4 that represents the vertex's position.

fragment_shader: &'a str

The text of the fragment shader stage

See the documentation of the vertex_shader. The inputs to this stage are defined as the fragment_input and the ouptut is gl_FragColor, a vec4 that represents the RGBA color of the fragment. Use the function texture to read values from GLSL textures; it will be converted to texture2D on the web backend.
