So the application itself is 2D and layered but I want to build the background bitmap from a Blender 3D model.
When I make an appeal to Saint Google there seem to be an awful lot of ways of getting to the desired result.
The process I have in mind is to do the following. Please comment on the practicality or otherwise of this approach.
Use a background thread to:
Load the model
Create a 3D buffer for rendering into
Render into the buffer
Copy the 3D buffer to a 2D buffer somewhere
The main loop will
Blit? copy the 2D background to the backbuffer of the swap chain
Overlay the background with various sprites
Swap buffers
Which leads to the following questions.
What is the best option for exporting a Blender model for use by DirectX.
Which API should I use to create a 3D buffer for rendering the model into? As it only gets rendered on scene changes, every 10-20 seconds, am I correct in assuming it shouldn't be part of the swap chain? In managing the background buffer is it best to, or must I, use a "dummy" device of some kind?
How do I turn a 3D buffer into a 2D bitmap for load into the 2D swap chain?
What is the best way to set up the 2D buffer so asto minimise the cost of the copy for every frame by the main loop?
