Android Vulkan, checking support anisotropics

How to check that device support anisotropics for Vulkan Graphics APi. For example for checking it on OPENGL used

String extension = GLES10.glGetString(GLES10.GL_EXTENSIONS);

and then check contains string "GL_EXT_texture_filter_anisotropic". How do it if used Vulkan Graphics api?

Solution

  • Anisotropic filtering is an optional device feature. You can query it with

    VkPhysicalDeviceFeatures supportedFeatures;
vkGetPhysicalDeviceFeatures(device, &supportedFeatures);

    supportedFeatures.samplerAnisotropy will contain a boolean stating if the feature is available.

    If you actually wanted to check for MSAA, then you can check supportedFeatures.limits.framebufferColorSampleCount and supportedFeatures.limits.framebufferDepthSampleCounts
