PBRMaterial

Qualified name: algan.rendering.shaders.materials.PBRMaterial

class PBRMaterial(color=None, *, roughness=1.0, metalness=0.0, emissive=Color([0., 0., 0., 0., 1.]), emissive_intensity=1.0, env_map_intensity=1.0, **kwargs)

Bases: Material

Metalness/roughness physically-based (Cook-Torrance) material.

Methods

get_shader_param_values	Map of {shader_param_name: value} matching this material's shader signature.
shader	MeshStandardMaterial: metalness/roughness Cook-Torrance PBR + emissive.

Attributes

applies_color

Whether the material's color should drive the mob's base color.

get_shader_param_values()

Map of {shader_param_name: value} matching this material’s shader signature. Base materials expose no extra parameters.

static shader(memory, vertex_location, vertex_normal, albedo_color, camera_location, light_origin, light_color, light_intensity, ambient_light_intensity, roughness=1.0, metalness=0.0, emissive=(0.0, 0.0, 0.0), emissive_intensity=1.0, env_map_intensity=1.0, flat_shading=0.0)

MeshStandardMaterial: metalness/roughness Cook-Torrance PBR + emissive.

Implements the GGX NDF, Smith geometry and Schlick Fresnel terms. The image-based environment reflection of the GLSL material is approximated by a constant ambient term scaled by env_map_intensity.

Parameters:

• light_intensity (float)

• ambient_light_intensity (float)

• roughness (float)

• metalness (float)

• emissive_intensity (float)

• env_map_intensity (float)

• flat_shading (float)
