Custom pointcloud shader about potree

[m-schuetz]

Materials for rgb, intensity, single color and height are now in the master and develop branches. Tweaking still necessary.

Hi Markus,
I would like to set a custom shader material for the point cloud, but when doing so, I get a ThreeJS ShaderMaterial instead of a Potree PointCloudMaterial, so I get the following error

potree.js:12437 Uncaught TypeError: scope.pointclouds[i].material.setClipBoxes is not a function
    at Potree.Viewer.update (potree.js:12437)
    at loop (potree.js:12943)

What I've done is either

• define a shaderMaterial from scratch and set vertex and fragment shaders - a bit modified from the current shaders of the point cloud
• clone the pointcloud.material using the threejs function, set its VertexShader and FragmentShader to what I want, but again same result
• update the shaders of the material of the point cloud directly, but the changes are not applied.

Can you tell me how I can achieve this feature of modifying portions (x, y, z, vcolor) of the shaders ?
Thanks a lot for your help again,
Jonathan

@jo-chemla Hi, Jonathan! I guess you have achieved yourself results. Could you share you experience?

Could you explain how does the shaders work? In what language have they been realized? Do you have any documentation regarding shaders?
