How to use a triangle mesh in vertexShader of ShaderEffect?
In QML, the ShaderEffect has a property "mesh" which defines the vertexes processed by its vertexShader. I noticed some examples of setting this mesh to GridMesh, but could not find any examples or info of using a triangle mesh.
Could anyone give me some recommendation/guidance or examples? Thank you in advance!
More specifically, I need to warp an image using a pair of triangle meshes. The vertexes in these two triangle meshes have been paired (one to one correspondence). I would like just to set the vertex correspondence in the vertexShader code.
