enables the shader (calls useProgram)

Renders a mesh using this shader, remember to use the function uniforms before to enable the shader

render several buffers with a given index buffer

Renders a range of a mesh using this shader

It extract all the info about the compiled shader program, all the info about uniforms and attributes. This info is stored so it works faster during rendering.

Returns the location of a uniform or attribute

Returns if this shader has an attribute with the given name

Returns if this shader has a uniform with the given name

Uploads a uniform to the Shader. You dont need to specify types, they are infered from the shader info. Shader must be binded!

Compiles one single shader source (could be gl.VERTEX_SHADER or gl.FRAGMENT_SHADER) and returns the webgl shader handler Used internaly to compile the vertex and fragment shader. It throws an exception if there is any error in the code

Allows to create a simple shader meant to be used to process a texture, instead of having to define the generic Vertex & Fragment Shader code

Given a source code with the directive #import it expands it inserting the code using Shader.files to fetch for import files. Warning: Imports are evaluated only the first inclusion, the rest are ignored to avoid double inclusion of functions Also, imports cannot have other imports inside.

Create a shader from two urls. While the system is fetching the two urls, the shader contains a dummy shader that renders black.

Returns a shader that blends two textures shader must have: u_factor, u_texture, u_texture2

Returns a shader used to apply gaussian blur to one texture in one axis (you should use it twice to get a gaussian blur) shader params are: vec2 u_offset, float u_intensity

Returns a shader ready to render a colored textured quad in fullscreen, use with Mesh.getScreenQuad() mesh shader params vec4 u_color and sampler2D u_texture

Returns a flat shader (useful to render lines)

Returns a shader to apply FXAA antialiasing params are vec2 u_viewportSize, vec2 u_iViewportSize or you can call shader.setup()

Returns a shader ready to render part of a texture into the viewport shader must have: u_position, u_size, u_viewport, u_transform, u_texture_area (vec4)

Returns a shader ready to render a quad with transform, use with Mesh.getScreenQuad() mesh shader must have: u_position, u_size, u_viewport, u_transform (mat3)

Returns a shader ready to render a textured quad in fullscreen, use with Mesh.getScreenQuad() mesh shader params sampler2D u_texture

Tells you which function to call when uploading a uniform according to the data type in the shader Used internally from extractShaderInfo to optimize calls

Renders a fullscreen quad with this shader applied

Uploads a set of uniforms to the Shader. You dont need to specify types, they are infered from the shader info.

It updates the code inside one shader
