class modules.render.shader.Shader(context, uid: str, templated: bool = False, compute: bool = False)#

Bases: object

__init__(context, uid: str, templated: bool = False, compute: bool = False)#

Load and parse GLSL shaders from .vert and .frag files

Parameters:

  • context (EmberEngine) – This is the main context of the application

  • uid (str) – The unique idenifier of the shader being initialized

  • templated (bool) – The version and defines will be set programmatically

bind_uniforms() → None#

Bind the found uniforms to the this shader program

inject_includes(src: str) → str#
inject_version_and_defines(src: str)#
load_compute(in_comp: str)#
load_program(in_vert: str, in_frag: str) → int#

Build and create the shader program from .vert and .frag shader

Parameters:

  • in_vert (str) – The content of a vertex shader

  • in_vert – The content of a fragment shader

Returns:

The index to a valid shader program in GPU memory

Return type:

int

load_shader(shader_type: OpenGL.constant.IntConstant, source: str)#

Compile shader from string

Parameters:

  • shader_type (OpenGL.constant.IntConstant) – The type of the shader: GL_VERTEX_SHADER or GL_FRAGMENT_SHADER

  • source (str) – The content of a shader file

parse_uniforms(shader: str) → None#

Dynamicly find and parse uniforms required by the shader

Parameters:

shader (str) – The content if a GLSL shader as string

printOpenGLError()#

Print any raised errors during GLSL parsing
