texture projection on meshes

This op allows you to project a texture onto an object such as a 3D mesh or MeshInstancer or Pointcloud. Should be placed after assigning a material.

When using this op to control PointSize, you can use an HDR/32bit texture to allow you to force values outside of the 0-1 range. You can also use the Amount parameter with values outside of the 0-1 range by manually entering them into the parameter panel or connecting a number op.

Inputs

render (Trigger)

Texture (Object)

currently texture is auto sized to a square ratio

Blending

blendMode index (integer /Number)

Amount (Number)

strength of texture colors or pointsize values

Target index (integer /Number)

color or pointsize

Scale (Number)

rescale incoming texture

Use Texture Alpha (boolean /Number)

applies alpha channel from incoming texture.

Position

Pos X (Number)

Pos Y (Number)

Rotation

Rot X (Number)

Rot Y (Number)

Rot Z (Number)

Mapping index (integer /Number)

XY, XZ, YZ, or screenspace

Discard (boolean /Number)

limit repeat of texture

WorldSpace (boolean /Number)

use world position coordinates

Outputs

trigger (Trigger)
