texture format utility about nri HOT 3 CLOSED

Hi! Thanks for your suggestion, it does make sense. There is const FormatProps& GetFormatProps(nri::Format format) (link) which is used internally and returns:

• stride between pixels in bytes
• block width in pixels
• "is integer" flag

It can be extended to include:

• NRI name as const char*
• "is normalized" flag
• "is float" flag
• "is signed" flag
• "is sRGB" flag
• "is compressed" flag
• channel count

This can be exposed in NRI API. Would it be enough? Which other data bits are you interested in? TIF is nice (at least in terms of functionality). If more is needed why not use TIF?

Some device specific texture properties are exposed in DeviceDesc:

    // Multi-sampling
    NRI_NAME(Sample_t) colorSampleMaxNum;
    NRI_NAME(Sample_t) depthSampleMaxNum;
    NRI_NAME(Sample_t) stencilSampleMaxNum;
    NRI_NAME(Sample_t) zeroAttachmentsSampleMaxNum;
    NRI_NAME(Sample_t) textureColorSampleMaxNum;
    NRI_NAME(Sample_t) textureIntegerSampleMaxNum;
    NRI_NAME(Sample_t) textureDepthSampleMaxNum;
    NRI_NAME(Sample_t) textureStencilSampleMaxNum;
    NRI_NAME(Sample_t) storageTextureSampleMaxNum;

you have a good point I've kind of rolled out my own code. that is good to know, I'll have to think about it.
