Rendering vertex arrays without creating a mesh

[Paul.Withers]

Hi,

I'm have code that renders a hierarchy of vertex buffers in Unigine and I have to create an ObjectMeshDynamic for each vertex array to render it.

The problem with that, is ObjectMeshDynamic objects are persistent, so if on the next frame i don't want to render that ObjectMeshDynamic i have to manually set it to be disabled, or delete it, which is really annoying because then i have to track all of the objects i have created.

What would be better if i could just pass a vertex / index array to Unigine to render that frame. Is that possible?

Cheers

Hi Paul,

I guess for that task you can try to use MeshDynamic instead of ObjectMeshDynamic: https://developer.unigine.com/en/docs/2.12/api/library/rendering/class.meshdynamic?rlang=cpp

Thanks!

Is there much of an associated performance penalty if i'm creating multiple MeshDynamics per frame?

It depends on the hardware itself, so it's hard to tell. The best way to find out is to write a small prototype and do some benchmarks with it.

Looks like MeshDynamic doesn't exist in Unigine 2.6.1, is there an equivalent?

I'm afraid there is no equivalent in the 2.6.x SDKs. Minimal requried version is 2.7.1 for this.
