Systems and methods for using EGL with an OpenGL API and a Vulkan graphics driver
A method for using an EGL driver to create a renderable surface for an OpenGL API is provided. The EGL driver and the OpenGL API can be used with a Vulkan graphics driver, a memory, at least one processor, and a module stored in the memory including computer instruction code that is executable by the at least on processor. The method includes creating an EGL display structure; initializing the EGL display structure by querying the Vulkan driver for attributes of a physical display; choosing an EGL configuring matching the provided attributes; and creating the EGL surface. A non-transitory computer readable medium having an EGL driver with computer instruction code that is executable by a processor to create a renderable surface for an OpenGL API is also provided.
1. A method for using an EGL driver to create a renderable surface for an OpenGL API, the EGL driver and the OpenGL API for use with a Vulkan graphics driver, a memory, at least one processor, and a module stored in the memory including computer instruction code that is executable by the at least one processor, the method comprising:
creating an EGL display structure;
initializing the EGL display structure by querying the Vulkan driver for attributes of a physical display;
receiving the attributes of the physical display from the Vulkan driver;
choosing an EGL configuration matching the attributes of the physical display; and
creating the EGL surface.
2. The method of claim 1 , further comprising
associating the EGL surface with the EGL display and a native windowing system.
3. The method of claim 1 , further comprising:
creating a graphics context;
associating the graphics context with the EGL display; and
associating the graphics context with the EGL surface to make the EGL surface a render target.
4. The method of claim 1 , wherein the step of creating the EGL display structure is by making an eglGetDisplay function call which uses the Vulkan graphics driver.
5. The method of claim 1 , wherein the step of initializing the EGL display structure is by making an egllnitialize function call which uses the Vulkan graphics driver.
6. The method of claim 1 , wherein the step of choosing the EGL configuring matching the attributes of the physical display is by making an eglChooseConfig function call which uses the Vulkan graphics driver.
7. The method of claim 1 , wherein the step of creating the EGL surface is by making an eglCreateWindowSurface function call which uses the Vulkan graphics driver.
8. The method of claim 1 , wherein the attributes of the physical display include color buffer size and/or depth buffer size.
9. A non-transitory, computer-readable medium, comprising: an EGL driver having computer instruction code that is executable by at least one processor and structured to cause the at least one processor to be configured to:
create an EGL display structure;
initialize the EGL display structure by querying the Vulkan driver for attributes of a physical display;
receive the attributes of the physical display from the Vulkan driver;
choose an EGL configuration matching the attributes of the physical display; and
create the EGL surface.
10. The non-transitory, computer-readable medium of claim 9 , wherein the EGL driver has computer instruction code that is executable by at least one processor and structured to cause the at least one processor to be configured to also:
associate the EGL surface with the EGL display and a native windowing system.
11. The non-transitory, computer-readable medium of claim 9 , wherein the EGL driver has computer instruction code that is executable by at least one processor and structured to cause the at least one processor to be configured to also:
create a graphics context;
associate the graphics context with the EGL display; and
associate the graphics context with the EGL surface to make the EGL surface a render target.
12. The non-transitory, computer-readable medium of claim 9 , wherein the step of create the EGL display structure is by making an eglGetDisplay function call which uses the Vulkan graphics driver.
13. The non-transitory, computer-readable medium of claim 9 , wherein the step of initialize the EGL display structure is by making an egllnitialize function call which uses the Vulkan graphics driver.
14. The non-transitory, computer-readable medium of claim 9 , wherein the step of choose the EGL configuring matching the attributes of the physical display is by making an eglChooseConfig function call which uses the Vulkan graphics driver.
15. The non-transitory, computer-readable medium of claim 9 , wherein the step of create the EGL surface is by making an eglCreateWindowSurface function call which uses the Vulkan graphics driver.
16. The non-transitory, computer-readable medium of claim 9 , wherein the attributes of the physical display include color buffer size and/or depth buffer size.
