How to render mask and other specific properties of the surface?

[Cloud Han]

I want to render some specific properties to images, say, mask and diffuse albedo

After digging into the code, I find

override def renderMask(parameters: RenderParameter, mask: MeshSurfaceProperty[Int]): PixelImage[Int] = maskRenderer((parameters, mask))

which requires a second parameter. But I don't know how to construct it.

More generally, I want to render diffuse albedo into image (aka, rendering the image simply with uniform illumination). And I find

  /**
    * render an arbitrary property on the mesh into buffer (rasterization)
    *
    * @param renderParameter scene description
    * @param mesh mesh to render, positions
    * @param property surface property to rasterize
    * @tparam A type of surface property
    * @return
    */
  def renderPropertyImage[A: ClassTag](renderParameter: RenderParameter,
                                       mesh: TriangleMesh3D,
                                       property: MeshSurfaceProperty[A]): PixelImage[Option[A]] = {
    TriangleRenderer.renderPropertyImage(mesh,
      renderParameter.pointShader,
      property,
      renderParameter.imageSize.width,
      renderParameter.imageSize.height
    )

in ParametricRenderer.scala

But I don't know how to obtain the property parameter...

Thanks ahead.

Hi,
the property parameter is attached to the VertexColorMesh3D object.
It is mesh.color, it has the type MeshSurfaceProperty[RGBA].
