Exposing of Framework buffers to the lua interface

[klepto2]

Hi,

 

how about exposing the various buffers from the Framework to lua? I was thinking about this feature last evening while porting my scattering code (bmx) to lua and checking out shadmars ocean shader (which is really awesome).

 

What would be the benefit of this feature:

- scripts and shader built outside of the framework may access these buffers

- different shaders can work together (eg: currently shadmar uses a cubemap to simulate the reflection, this breaks a working combination of mine (scattering shader) and the ocean shader.

 

What may solve this:

- Expose the different buffers to lua

- Expose functions which can produce reflections independent from the framework water

 

I don't know if this feature is realistc, but i think it might be essential for combined user defined environment scripts.

 

thx in advance

If we could fetch the reflectioncam within the editor it would be great

How is this done for the default waterplane?, I suspect there is some code behind the scenes we can't get to?

I haven't tried this in lua shadmar, but in C++ we can get the world and camera from each framework layer. Also, you should be able to just look at the lua code for the default waterplane to see how he does it.

Unfortunatly the waterplane is handled internally and the script only uses the framework commands for the water.

But as we can access the world and cameras of the specific layers it might be possible to port the DrawReflection code to lua. One problem might be the background rendering, as the skybox is handled also internally we need to render everything like the normal render which may lead to performance issues.

its been posted as a bug and was reported that it was fixed - but I cannot find any sign that it has been done.

Edit- the gbuffer has been exposed, but i do not know if the other buffers have been or not...
