PYME.LMVis.shader_programs.PointSpriteShaderProgram module¶

class PYME.LMVis.shader_programs.PointSpriteShaderProgram.GaussTexture¶

Bases: object

bind_texture(uniform_location)¶

This methods binds exactly one texture. Parameters ———- uniform_location: int, defines the uniform location, use shader_program.get_uniform_location

Returns

delete_texture()¶

static disable_texture_2d()¶

static enable_texture_2d()¶

load_texture(size=31, sigma=5, normalize_sum=False)¶

This method create a gauss kernel texture and stores it on the graphics card. The max amplitude of the kernel is 1. Parameters ———- size size of the kernel sigma of the kernel

Returns

size correction factor is a factor that should be multiplied on the texture size.
That way sprites don’t appear smaller than opaque dots
