working example, renders all gui controls.
We still cant render a scene, something to do with the constant buffer at slot 0 of the vertex shader being too small..... gotta figure this one out..................
Refactored DX Shader compilation and reflection to be more similar to opengl
Added support for more than 1 const buffer per shader stage.
This is boilerplate code, no functionality yet, that will be added in further commits. Though this builds without errors do not try and run it at this point.
Updated IES loader to use torque math functions and calls in the problem areas for mac and linux.
New F32_MIN_EX which is lower than F32_MIN (required for ies profiles)
ADDED: Ability to add IES profile as the cookie texture slot in both point lights and spot lights
TODO:
Have the IES Profile also drive the settings for the lights.
Make it work with Cookie textures. IES profiles are to be another slot in the advanced light section.
-Removed LPNG
-Removed LJPEG
-Re-Added DefferredPNGWriter from rextimmy stb work
Commented out lines about file saving and reading in gfont, these are good for debugging font saves.
it's getting there, but there have been a few spots noted where it eroneously corrupts text, so we'll have to pull this back out for a bit barring a proper resolution
review of per and post bake protocols showed that the CAPTURING shader macro was not being properly recompiled in. as opengl was not playing nice with a simple batch shader recompilation for all effected shaders, a full lightmanager restart is at time of writing required. once we have a proper globally cached scene structure stored off GPU side, we'll want to change GFXShader::addGlobalMacro("CAPTURING", String("1")); on over to dirtying that value in the cached buffer via setting a shader global uniform
review of prefilter examples shows a fixed sample count of 1024 across multiple implementations, so we'll use the standard barring further research into where that number is comming from for a scalar approach
review of gl shaders shows a doubleup in compiled state testing, so slimmed that down and added additional debugging reports
Added support for .hdr format, atm just being converted to ldr after the exposure is applied.
cleanup dds file
PNG skips 16bit altogether at the moment for textureArray issues.
Generating image previews of image assets was failing
DDS remove redundant check for stream status.
STB requires the file to be free before being written to, move check to make sure we can open the path into gBitmap and remove FileStream checks from everywhere else.
The fix adds a sanity check to the D3D and GL device enumeration function that exits early if there's no registered display from the OS(implying it's running in commandline).
With newer versions of SDL, attempting to enumerate the GL device causes a segfault because the OS will return back a valid context, but the context isn't actually valid. So when tested against, it crashes. Avoiding enumerating the device when you're not in a position to render works around the issue.
TODO: If the machine is running in terminal-only mode, and thus has no valid render context, but still has a monitor plugged into the machine, it can sidestep the sanity check and still result in a segfault. Need a more robust check for that circumstance in a future fix.
Workaround: MacOS does not have access to glClipControl.
Because the lower range of the 32F buffer is not available using this workaround, the improvements to depth behavior from depth reversal will be limited on MacOS. Behavior is equivalent to reversed depth on a 24UINT buffer; Better than stock, but not dramatically.
-Adds reversed depth projection model, dramatically increasing depth buffer effective resolution.
-Adds 32F depth 8U stencil format GFXFormatD32FS8X24 (following DX naming conventions). Note this is a 64-bit format, and likely not suitable for mobile platforms. Revert to GFXFormatD24S8 in renderManager.tscript for mobile & "ancient" platforms.
-Corrects alignment of texture type details array.
