Replace texture image data #147

Closed veeenu closed 6 months ago

veeenu commented 8 months ago

Currently, a texture can only be loaded once via RenderEngine::load_image and its contents cannot be changed.

A public RenderEngine::replace_image method should be created to make this happen.

For dx11 and dx12, uploadbuffer RowPitch must be aligned to 256 bytes (64 pixels). Might also fix this to support images with arbitrary width.

That's an unrelated issue -- could you please open a new one so we can track that separately?

I did some experiments early today, but on an old version 799032ba from Jan, when there was only DX12 renderer.

I split create_texture_inner into create_texture_inner+ upload_texture_inner, then added replace_image to RenderEngine.

Here is the quick (and dirty) patch file for future reference. I haven't written any raw DX12 before, so there might be some bugs. split_create_texture_and_upload_texture.patch on 799032ba

When I have some more spare time, I will take a look at renderers of other APIs.

That's a good starting point, thank you!
