Types

type Shader

type Shader uint32

Shader used to interact with an opengl shader.

func CreateShader

func CreateShader(vertexShaderSource, fragmentShaderSource string) *Shader

CreateShader used to create a shader from the given source.

func (*Shader) BindFragDataLocation

func (s *Shader) BindFragDataLocation(loc string)

BindFragDataLocation Sets the variable from which the fragment shader draws its result.

func (*Shader) GetAttributeLocation

func (s *Shader) GetAttributeLocation(name string) uint32

GetAttributeLocation Gets the location of the variable name in the shader.

func (*Shader) GetUniformLocation

func (s *Shader) GetUniformLocation(name string) int32

GetUniformLocation Gets the location of the uniform variable name in the shader.

func (*Shader) Use

func (s *Shader) Use()

Use Sets this shader as the active one.
