Loads a shader into a Py5Shader object.


Loads a shader into a Py5Shader object. The shader file must be located in the Sketch’s “data” directory to load correctly. Shaders are compatible with the P2D and P3D renderers, but not with the default renderer.

Alternatively, the file maybe be loaded from anywhere on the local computer using an absolute path (something that starts with / on Unix and Linux, or a drive letter on Windows), or the filename parameter can be a URL for a file found on a network.

If the file is not available or an error occurs, None will be returned and an error message will be printed to the console. The error message does not halt the program, however the None value may cause an error if your code does not check whether the value returned is None.

This method is the same as load_shader() but linked to a Py5Graphics object. To see example code for how it can be used, see load_shader().

Underlying Processing method: PGraphics.loadShader


load_shader(frag_filename: str, /) -> Py5Shader
load_shader(frag_filename: str, vert_filename: str, /) -> Py5Shader


  • frag_filename: str - name of fragment shader file

  • vert_filename: str - name of vertex shader file
