* gallium: add bits for clipping points as tris (d3d-style)Roland Scheidegger2014-01-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | OpenGL does whole-point clipping, that is a large point is either fully clipped or fully unclipped (the latter means it may extend beyond the viewport as long as the center is inside the viewport). d3d9 (d3d10 has no large points) however requires points to be clipped after they are expanded to a rectangle. (Note some IHVs are known to ignore GL rules at least with some hw/drivers.) Hence add a rasterizer bit indicating which way points should be clipped (some drivers probably will always ignore this), and add the draw interaction this requires. Drivers wanting to support this and using draw must support large points on their own as draw doesn't implement vp clipping on the expanded points (it potentially could but the complexity doesn't seem warranted), and the driver needs to do viewport scissoring on such points.

| | | | | | | | | | With this patch llvmpipe will adhere to the ARB_depth_clamp enabled state when clamping the fragment's zw value. To support this, the variant key now includes the depth_clamp state. key->depth_clamp is derived from pipe_rasterizer_state's (depth_clip == 0), thus depth clamp is only enabled when depth clip is disabled.

* gallium: interface changes necessary to implement transform feedback (v5)Marek Olšák2011-12-151-18/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Namely: - EXT_transform_feedback - ARB_transform_feedback2 - ARB_transform_feedback_instanced The old interface was not useful for OpenGL and had to be reworked. This interface was originally designed for OpenGL, but additional changes have been made in order to make st/d3d1x support easier. The most notable change is the stream-out info must be linked with a vertex or geometry shader and cannot be set independently. This is due to limitations of existing hardware (special shader instructions must be used to write into stream-out buffers), and it's also how OpenGL works (stream outputs must be specified prior to linking shaders). Other than that, each stream output buffer has a "view" into it that internally maintains the number of bytes which have been written into it. (one buffer can be bound in several different transform feedback objects in OpenGL, so we must be able to have several views around) The set_stream_output_targets function contains a parameter saying whether new data should be appended or not. Also, the view can optionally be used to provide the vertex count for draw_vbo. Note that the count is supposed to be stored in device memory and the CPU never gets to know its value. OpenGL way | Gallium way ------------------------------------ BeginTF = set_so_targets(append_bitmask = 0) PauseTF = set_so_targets(num_targets = 0) ResumeTF = set_so_targets(append_bitmask = ~0) EndTF = set_so_targets(num_targets = 0) DrawTF = use pipe_draw_info::count_from_stream_output v2: * removed the reset_stream_output_targets function * added a parameter append_bitmask to set_stream_output_targets, each bit specifies whether new data should be appended to each buffer or not. v3: * added PIPE_CAP_STREAM_OUTPUT_PAUSE_RESUME for ARB_tfb2, note that the draw-auto subset is always required (for d3d10), only the pause/resume functionality is limited if the CAP is not advertised v4: * update gallium/docs v5: * compactified struct pipe_stream_output_info, updated dump/trace

* Gallium: Increase PIPE_MAX_CLIP_PLANES to 8.Paul Berry2011-09-201-1/+1
| | | | | | | | Since Mesa is now capable of supporting up to 8 clipping planes instead of 6, this patch updates Gallium internals to support 8 clipping planes as well. Reviewed-by: Brian Paul <brianp@vmware.com>
* gallium: extend resource_resolve to accommodate BlitFramebufferChristoph Bumiller2011-08-041-0/+28
| | | | | | | | | | | | | Resolve via glBlitFramebuffer allows resolving a sub-region of a renderbuffer to a different location in any mipmap level of some other texture, and, with a new extension, even scaling. Therefore, location and size parameters are needed. The mask parameter was added because resolving only depth or only stencil of a combined buffer is possible as well. Full information about the blit operation allows the drivers to take the most efficient path they possibly can.
