- handle portals in sprite lighting, but do not use the playsim's utility functions for efficiency.

- fixed weapon positioning again, after finding out that the first fix just worked around the actual problem: The entire coordinate calculation must be done in floating point with no integer math at all. Due to roundoff errors the stored int values needed for wall and flat placement significantly lack precision and with the high scaling factor that needs to be used for weapon HUD sprites these can easily become several pixels. After fixing this the border around sprite textures could be reverted to one pixel again.
...
- fixed: The 'may not be expanded' state should be stored in the texture and reused later. This also needs to revalidate the material if it decides that expansion should be disallowed.

- calculate weapon positions fully in floating point to avoid roundoff errors.
...
- In order to get reliable results the empty border around scaled sprites must be the same scale as the sprite (i.e. 2 pixels for 2x scale and 4 pixels for 4x scale.)

- fixed: The brightfog flag in the GL related map settings was never initialized.
...
- fixed: brightfog should not disable colored lighting for the weapon sprite.

- we don't really need a bBrightmap in a texture. All it did was duplicate some functionality of bMasked.
...
- renamed bBrightmapDisablesFullbright flag.

- fixed: Since the engine can no longer change renderers on the fly, thanks to ZDoom's messed up video startup code, we have to abort with a fatal error if we can't create a GL context. Otherwise the user will never see a meaningful message.

- route texture binding through the renderstate class for better control. Currently it's just a direct passthrough but this will change.

major cleanup of the texture manager:
...
- use sampler objects to avoid creating up to 4 different system textures for one game texture just because of different clamping settings.
- avoids flushing all textures for change of texture filter mode.
- separate sprite and regular dimensions on the material level to have better control over which one gets used. It's now an explicit parameter of ValidateTexture. The main reason for this change is better handling of wall sprites which may not be subjected to such handling.
- create mipmaps based on use case, not texture type.
- allows removal of FCloneTexture hack for proper sharing of the same sprite for decals and other purposes.
- better precaching of skyboxes.

removed all GL 2.x code.
...
After thinking about it for a day or so I believe it's the best option to remove all compatibility code because it's a major obstacle for a transition to a core profile.

- use a software buffer for immediate mode rendering. This allows using the regular buffer code to collect data for both render modes and allows removal of a lot of duplicated code.
2014-06-15 01:14:41 +02:00
Christoph Oelckers

- put all the common part of buffer based drawing into a separate method of the vertex buffer.

shader rework
...
All those special shaders have been merged together.
Mostly working but the non-shader lighting seems a bit broken.

Do not use the shader to handle STYLEF_RedIsAlpha.
...
Turns out that the name doesn't accurately describe what it does.
It is correct for images that come with their own palette or are true color.
But for images using the game palette it doesn't use the red channel to determine translucency but the palette index! Ugh...
This means it cannot be done with a simple operation in the shader because it won't get a proper source image. The only solution is to create a separate texture.

- removed all code that mixes together the different lighting methods. Now everything goes through the 3 different light parameters in the render state.
...
- removed cm parameter from many functions.

Ok, it had to be done: Removed shader support for pre GLSL 1.3/GL 3.0 hardware. The compromises needed to accomodate these are just too bad and would block any attempt at streamlining the code.
