Graphics anti-aliasing resolve with stencil mask
An embodiment of a graphics apparatus may include a mask buffer to store a mask, a shader communicatively coupled to the mask buffer to apply the mask to a first shader pass, and a resolver communicatively coupled to the mask buffer to apply the mask to a resolve pass. The resolver may be configured to exclude a sample location not covered by the mask in the resolve pass. Other embodiments are disclosed and claimed.
1. At least one non-transitory computer readable storage medium comprising instructions stored thereon that if executed by one or more of a plurality of processing cores that support foveated rendering based on eye-tracking information, cause the one or more of the plurality of processing cores to:
assign a first mask value to a first portion of an image area based on the eye-tracking information;
assign a second mask value to a second portion of the image area;
cause the first portion of the image area to be rendered at a first rate;
cause the second portion of the image area to be rendered at a second rate; and
associate the first mask value with a third portion of the image area based on a change in the eye-tracking information;
wherein the second portion is a region outside of the first portion,
further wherein the first rate is different than the second rate.
2. The at least one non-transitory computer readable storage medium of claim 1 , wherein the first and second rates correspond to first and second shading rates, respectively.
3. The at least one non-transitory computer readable storage medium of claim 1 , wherein the second rate is half of the first rate.
4. The at least one non-transitory computer readable storage medium of claim 1 , wherein the first rate is higher than the second rate.
5. A computing system comprising:
a graphics processor;
a central processing unit; and
a memory including a set of instructions, which when executed by one or more of the graphics processor or the central processing unit, cause the computing system to:
assign a first mask value to a first portion of an image area based on eye-tracking information;
assign a second mask value to a second portion of the image area;
cause the first portion of the image area to be rendered at a first rate;
cause the second portion of the image area to be rendered at a second rate; and
associate the first mask value with a third portion of the image area based on a change in the eye-tracking information;
wherein the second portion is a region outside of the first portion,
further wherein the first rate is different than the second rate.
6. The system of claim 5 , wherein the first and second rates correspond to first and second shading rates, respectively.
7. The system of claim 5 , wherein the second rate is half of the first rate.
8. The system of claim 5 , wherein the first rate is higher than the second rate.
9. A method comprising:
assigning a first mask value to a first portion of an image area based on eye-tracking information;
assigning a second mask value to a second portion of the image area;
causing the first portion of the image area to be rendered at a first rate;
causing the second portion of the image area to be rendered at a second rate; and
associating the first mask value with a third portion of the image area based on a change in the eye-tracking information;
wherein the second portion is a region outside of the first portion,
further wherein the first rate is different than the second rate.
10. The method of claim 9 , wherein the first and second rates correspond to first and second shading rates, respectively.
11. The method of claim 9 , wherein the second rate is half of the first rate.
12. The method of claim 9 , wherein the first rate is higher than the second rate.
