class pyrender.Primitive(positions, normals=None, tangents=None, texcoord_0=None, texcoord_1=None, color_0=None, joints_0=None, weights_0=None, indices=None, material=None, mode=None, targets=None, poses=None)

Bases: object

A primitive object which can be rendered.

Parameters:

• positions ((n, 3) float) – XYZ vertex positions.
• normals ((n, 3) float) – Normalized XYZ vertex normals.
• tangents ((n, 4) float) – XYZW vertex tangents where the w component is a sign value (either +1 or -1) indicating the handedness of the tangent basis.
• texcoord_0 ((n, 2) float) – The first set of UV texture coordinates.
• texcoord_1 ((n, 2) float) – The second set of UV texture coordinates.
• color_0 ((n, 4) float) – RGBA vertex colors.
• joints_0 ((n, 4) float) – Joint information.
• weights_0 ((n, 4) float) – Weight information for morphing.
• indices ((m, 3) int) – Face indices for triangle meshes or fans.
• material (Material) – The material to apply to this primitive when rendering.
• mode (int) –

  The type of primitives to render, one of the following:

  • 0: POINTS
  • 1: LINES
  • 2: LINE_LOOP
  • 3: LINE_STRIP
  • 4: TRIANGLES
  • 5: TRIANGLES_STRIP
  • 6: TRIANGLES_FAN
• targets ((k,) int) – Morph target indices.
• poses ((x,4,4), float) – Array of 4x4 transformation matrices for instancing this object.
