Buffer to Texture conversion.

[Thareh]

Hi!

What's the best way to convert a buffer to a texture?

The only way I know of is using GetColorBuffer, but that also links the buffer to the texture and therefore doesn't fit my purpose.

 

Thanks

Oh and I'm posting here because I didn't get much response on my other thread.

You can use CopyBuffer(GetColorBuffer(),BUFFER_COLOR) to get only the texture which is not linked to the original buffer.

Thank you, I'm aware of that but I don't want any linking with any buffers.

I'm not sure they're freed correctly when linked to a texture, my program crashes after x amount of GetColorBuffers.

You should always free the buffer yourself and not wait for the engine to do it.

There's no FreeBuffer command in BlitzMax, I'm just using Buffer = Null.

I'm not sure what FreeBuffer() does, but I would assume it also sets the buffer to null and then calls garbage collection to make sure it's released immediately and not at some random point which will make your program crash.

Even if I can get it freed correctly I'd still prefer a way without having to copy the buffer.

Creating a buffer or doing GetColorBuffer is pretty slow, my program freezes like 250ms on my Laptop when I call them.

(Which is not good since I use A LOT of both of these commands for my Render to Texture interface)

I think I've got the buffers to free correctly now!

But still the performance on using CreateBuffer and GetColorBuffer to do a 'Render to Texture' routine is very poor :/

There must be a better way of doing this! >.<
