GL_TEXTURE_BASE_LEVEL matches the basetexture::SetLOD functionality.
D3DSAMP_MAXMIPLEVEL essentially does the same as SetLOD. The test included in
this patch shows that the smallest mipmap level is used.
This reduces the number of srgb switching reloads quite a lot. The only
situation in which a reload is needed is if the rgb copy is modified on the GL
side and the srgb copy is needed.
Note that minMipLookup and magLookup aren't particularly safe to use,
they're global arrays initialized from IWineD3DImpl_FillGLCaps(). The same
goes for the other global dynamic lookup tables.
This is cleaner than the if statements in the code. Also np2 textures
should in theory support linear filtering, but fglrx doesn't seem to
like it. This needs further investigation. So far we've never used
linear filtering on np2 textures, so there should not be a
regression. Furthermore I think shader support is more important than
filtering, since NP2 textures are mostly used for 1:1 copying to the
screen.
ATI cards prior to the radeon HD series did not have unconditional non
power of two support. So far we've used texture_rectangle for that, or
created a bigger power of two texture with padding. This had the
disadvantage that we had to correct the coordinates, which causes
extreme problems with shaders(doesn't work, pretty much).
Both the MacOS and the fglrx driver have support for
GL_ARB_texture_non_power_of_two, and run it on the hardware as long as
we stay within the texture_rectangle limitations. This allows us to
have conditional non power of two textures with normalized
coordinates. This patch adds an internal extension, and the code
creates a regular GL_TEXTURE_2D texture with NP2 size, but refuses
mipmapping, filtering and texture_rectangle incompatible
operations. This makes np2 textures work with shaders on fglrx and
macos.
This makes it easier to make this a per texture / per adapter property.
Somewhen we should rename the remaining lookup type in the general
lookup table to wraplookup.
Conditional NP2 textures in Direct3D do not support D3DTADDRESS_WRAP
texture addressing. Similarly, GL_ARB_texture_rectangle textures do
not support GL_REPEAT. This patch adds a test which shows that _WRAP
clamps to the texture edge and implements that.
relate to the opengl texture object will only be updated when they are
out of sync, this reduces the number of texture object state changes
during game play in Axis and allies from several hundreds to 0 or 1.
any objects referenced by the internal stateblock are released when
the stateblock is released (we don't reference count while a
stateblock is recording, so recorded stateblocks have no references to
clean up).
the first time around.
Replace some calls to cubetexture in basetexture to calls to
basetexture.
Check that the level isn't out of bounds in calls to texture.
the interface but it is more correct way (Microsoft even have a
resource type of volume).
- Moved usage, format, allocatedMemory and size onto the resource
class structure.
- Refactored Preload for classes that inherit BaseTexture, preload now
binds the texture instead of bind texture calling preload, bindTexture
allocated a glTexture if there isn't one.
- Added two new class static members BaseTexture_CleanUp and
Resource_CleanUp that should be called by classes that implement
BaseTexture or Resource.
Added BindTexture, GetTextureDimensions, UnBindTexture.
Proper GetContainer support for surface.
SetContainer added to surface and volume.
SetInPbufferState added to surface (until gl context management is
implemented).
Minor changes:
- BaseTexture no longer 'holds' a reference to IWineD3DDevice to
prevent circular referencing.
- Better managment of referinging for texture.
- Some TODO's for implementing a context manager.
- Better preload implementation.
- Fix compile warning in device.c Set/GetSamplerState.
- Add QueryInterface support for surface.
- Format X8R8G8B8 added to locking.
