Abstract

Systems, apparatuses and methods may provide for technology that determines a stencil value and uses the stencil value to control, via a stencil buffer, a coarse pixel size of a graphics pipeline. Additionally, the stencil value may include a first range of bits defining a first dimension of the coarse pixel size and a second range of bits defining a second dimension of the coarse pixel size. In one example, the coarse pixel size is controlled for a plurality of pixels on a per pixel basis.

Claims (61)

1. A system comprising:

a display;

a two-dimensional (2D) texture memory;

a graphics pipeline coupled to the display; and

logic to:

identify a first level of detail for a scene,

determine a first 2D texture value based on the first level of detail, wherein the first 2D texture value corresponds to a first pixel size,

apply the first 2D texture value to the 2D texture memory to store the first 2D texture value in the 2D texture memory,

identify a second level of detail for the scene, and

determine a second 2D texture value based on the second level of detail, wherein the second 2D texture value is to correspond to a second pixel size,

wherein the first level of detail is to be greater than the second level of detail, and further wherein the first pixel size is to be smaller than the second pixel size.

2. The system of claim 1 , wherein the first level of detail is to include occlusion information.

3. The system of claim 1 , wherein the logic is to:

apply the second 2D texture value to the 2D texture memory to store the second 2D texture value in the 2D texture memory.

4. The system of claim 1 , wherein the first 2D texture value is to include a first range of bits defining a first dimension of the first pixel size and a second range of bits defining a second dimension of the first pixel size.

5. The system of claim 1 , wherein the logic is to:

apply the first 2D texture value to a location in the 2D texture memory, wherein the location is to correspond to a pixel in the scene.

6. An apparatus comprising:

a substrate; and

logic coupled to the substrate, wherein the logic is implemented in one or more of configurable logic or fixed-functionality hardware logic, the logic coupled to the substrate to:

identify a first level of detail for a scene,

determine a first 2D texture value based on the first level of detail, wherein the first 2D texture value corresponds to a first pixel size,

apply the first 2D texture value to a 2D texture memory to store the first 2D texture value in the 2D texture memory,

identify a second level of detail for the scene, and

determine a second 2D texture value based on the second level of detail, wherein the second 2D texture value is to correspond to a second pixel size,

wherein the first level of detail is to be greater than the second level of detail, and

further wherein the first pixel size is to be smaller than the second pixel size.

7. The apparatus of claim 6 , wherein the first level of detail is to include occlusion information.

8. The apparatus of claim 6 , wherein the logic coupled to the substrate is to:

apply the second 2D texture value to the 2D texture memory to store the second 2D texture value in the 2D texture memory.

9. The apparatus of claim 6 , wherein the first 2D texture value is to include a first range of bits defining a first dimension of the first pixel size and a second range of bits defining a second dimension of the first pixel size.

10. The apparatus of claim 6 , wherein the logic coupled to the substrate is to:

apply the first 2D texture value to a location in the 2D texture memory, wherein the location is to correspond to a pixel in the scene.

11. A method comprising:

identifying, with a processor, a first level of detail for a scene;

determining, with the processor, a first 2D texture value based on the first level of detail, wherein the first 2D texture value corresponds to a first pixel size;

applying, with the processor, the first 2D texture value to a 2D texture memory to store the first 2D texture value in the 2D texture memory;

identifying, with the processor, a second level of detail for the scene; and

determining, with the processor, a second 2D texture value based on the second level of detail, wherein the second 2D texture value is to correspond to a second pixel size;

wherein the first level of detail is to be greater than the second level of detail, and

further wherein the first pixel size is to be smaller than the second pixel size.

12. The method of claim 11 , wherein the first level of detail includes occlusion information.

13. The method of claim 11 , further comprising:

applying, with the processor, the second 2D texture value to the 2D texture memory to store the second 2D texture value be stored in the 2D texture memory.

14. The method of claim 11 , wherein the first 2D texture value includes a first range of bits defining a first dimension of the first pixel size and a second range of bits defining a second dimension of the first pixel size.

15. The method of claim 11 , further comprising:

applying, with the processor, the first 2D texture value to a location in the 2D texture memory corresponding to a pixel in the scene.

16. At least one non-transitory computer readable storage medium comprising a set of instructions, which when executed by a computing system, cause the computing system to:

identify a first level of detail for a scene;

determine a first 2D texture value based on the first level of detail, wherein the first 2D texture value corresponds to a first pixel size;

apply the first 2D texture value to a 2D texture memory to store the first 2D texture value in the 2D texture memory;

identify a second level of detail for the scene; and

determine a second 2D texture value based on the second level of detail, wherein the second 2D texture value is to correspond to a second pixel size;

wherein the first level of detail is to be greater than the second level of detail; and

further wherein the first pixel size is to be smaller than the second pixel size.

17. The at least one non-transitory computer readable storage medium of claim 16 , wherein the first level of detail is to include occlusion information.

18. The at least one non-transitory computer readable storage medium of claim 16 , wherein the instructions, when executed, cause the computing system to:

apply the second 2D texture value to the 2D texture memory to store the second 2D texture value in the 2D texture memory.
