OGLLinesShader (object)¶

バージョン 1.12.0 で追加.

The OGLLinesShader inherits the OGLInlineShader. It extends the OGLInlineShader for shading with a specialized lines shading model..

Uniforms¶

Name	Type	Description	Default
u_light0Position	Vec3	Position of the first light	Position of the camera

u_ambientColor	Color	Ambient color component	Color(0.05, 0.05, 0.05)
u_rootColor	Color	Color at the start of each line (ratio == 0.0)	Color(0.1, 0.1, 0.1)
u_tipColor	Color	Color at the end of each line (ratio == 1.0)	Color(1.0, 1.0, 1.0)
u_specularColor	Color	Specular color component	Color(0.2, 0.2, 0.2)
u_specularFactor	Color	Specular distribution factor	16.0
