Title: getting vertex data back from the VBO
Post by: Aisaaax on July 17, 2020, 09:28:00
Can I do that? Also, how expensive is it to get the triangles from VBO, add or modify that data on CPU, and then load it back to the GPU as a new array? If I do it like 10 times a second, will it greatly impact my performance?
