Méthode Description
Bind ( Shader shader ) : void

Bind a shader for rendering
FromString ( string vertexShader, string geometryShader, string fragmentShader ) : Shader

Load the vertex, geometry and fragment shaders from source code in memory

This function loads the vertex, geometry and fragment shaders. Pass NULL if you don't want to load a specific shader. The sources must be valid shaders in GLSL language. GLSL is a C-like language dedicated to OpenGL shaders; you'll probably need to read a good documentation for it before writing your own shaders.

SetUniform ( string name, CurrentTextureType current ) : void

Specify current texture as \p sampler2D uniform

This overload maps a shader texture variable to the texture of the object being drawn, which cannot be known in advance. The second argument must be CurrentTexture. The corresponding parameter in the shader must be a 2D texture (sampler2D GLSL type).

Example: uniform sampler2D current; // this is the variable in the shader shader.setUniform("current", Shader.CurrentTexture);

SetUniform ( string name, Glsl vector ) : void

Specify value for vec2 uniform
SetUniform ( string name, Texture texture ) : void

Specify a texture as sampler2D uniform

name is the name of the variable to change in the shader. The corresponding parameter in the shader must be a 2D texture (sampler2D GLSL type).

Example: uniform sampler2D the_texture; // this is the variable in the shader sf::Texture texture; ... shader.setUniform("the_texture", texture); It is important to note that texture must remain alive as long as the shader uses it, no copy is made internally.

To use the texture of the object being drawn, which cannot be known in advance, you can pass the special value Shader.CurrentTexture: shader.setUniform("the_texture", Shader.CurrentTexture);

SetUniform ( string name, bool x ) : void

Specify value for bool uniform
SetUniform ( string name, float x ) : void

Specify value for float uniform
SetUniform ( string name, int x ) : void

Specify value for int uniform
SetUniformArray ( string name, Glsl array ) : void

Specify values for vec2[] array uniforms
SetUniformArray ( string name, float array ) : void

Specify values for float[] array uniforms
Shader ( IntPtr ptr ) : System

Construct the shader from a pointer
Shader ( Stream vertexShaderStream, Stream geometryShaderStream, Stream fragmentShaderStream ) : System

Load the vertex, geometry and fragment shaders from custom streams

This function loads the vertex, geometry and fragment shaders. Pass NULL if you don't want to load a specific shader. The sources must be valid shaders in GLSL language. GLSL is a C-like language dedicated to OpenGL shaders; you'll probably need to read a good documentation for it before writing your own shaders.

Shader ( string vertexShaderFilename, string geometryShaderFilename, string fragmentShaderFilename ) : System

Load the vertex, geometry and fragment shaders from files

This function loads the vertex, geometry and fragment shaders. Pass NULL if you don't want to load a specific shader. The sources must be text files containing valid shaders in GLSL language. GLSL is a C-like language dedicated to OpenGL shaders; you'll probably need to read a good documentation for it before writing your own shaders.
