How to create a 3D object using Mesh and MeshRenderer

[NgVThangBz]

i found example of: MeshRenderer::create(filePath) in test-cpp
however i need to create a custom object eg: (sphere, cube...)
by providing vertices, edges.... (like DrawNode)
how can i create it,
anyone have experience with it

[iRoboco]

look at this code tests/cpp-tests/Source/MeshRendererTest/DrawNode3D.cpp
and this method DrawNode3D::drawCube
I think you can draw other primitives in a similar way

[NgVThangBz]

DrawNode3D just a simple version of drawing edges,
but a cube needs more than that, we need to provide vertices, edges, faces...
I think I should use Mesh to create this data, then use MeshRender to draw it,
similar to rendering 3D files like .c3t and .obj
but I don't know how to create a valid Mesh
