OGLSurfaceOverlayShader (object)¶

バージョン 1.12.0 で追加.

The OGLSurfaceOverlayShader is used for rendering surface attributes as a semitransparent colored overlay on top of existing geometry. It offsets the overlay geometry in the -Z space to ensure no z-fighting occurs between the underlying geometry and the overlay.

This shader is often used to display paintable weightmaps over the top of geometry in the viewport.

Uniforms¶

Name	Type	Description	Default
u_color	Color	Color of the map drawn	Color(1.0, 0.0, 0.0)
u_light0Position	Vec3	Position of the first light	Position of the camera
u_light0Color	Color	Color of the first light	Color(1.0, 1.0, 1.0)
u_normalIsTangent	Integer	Flag defining normal type	0
u_doubleSided	Integer	Flag defining backface shading model	0

Attributes¶

Name	Type	Description
positions	Vec3	Geometry positions
normals	Vec3	Geometry normals
weightMap	Scalar	Geometry attribute being used to color the surface.
