RTCSETGEOMETRYENABLEFILTERFUNCTIONFROMARGUMENTS(3embree4)

💖 rtcSetGeometryEnableFilterFunctionFromArguments — bestie edition 💖

okay so this is a page from the Embree Ray Tracing Kernels 4 manuals (3embree4, section 3, iykyk) and it's all about one lil function that flips a switch on a geometry. let's get into it 🫶

✨ NAME ✨

rtcSetGeometryEnableFilterFunctionFromArguments — turns on the argument filter functions for a geometry. that's the whole job bestie 💅

🌸 SYNOPSIS 🌸

#include <embree4/rtcore.h>

void rtcSetGeometryEnableFilterFunctionFromArguments(
   RTCGeometry geometry, bool enable);

🦋 DESCRIPTION 🦋

so what does this actually do? it lets the filter function that you passed in through RTCIntersectArguments or RTCOccludedArguments actually get invoked on your intersect and occluded queries. literally that's it, that's the vibe ✨

• if enable is true → the argument filter function invocation is enabled for the geometry 💖
• otherwise → it's disabled 🙈
• and heads up: by default, the invocation of the argument filter function is disabled for some geometry. so if it's not working, that might be why bestie 😭

there's also another way to make it happen: the argument filter function invocation can get enforced for each geometry by using the RTC_RAY_QUERY_FLAG_INVOKE_ARGUMENT_FILTER ray query flag, which can get passed to the rtcIntersect and rtcOccluded functions. no cap. go read Section [rtcInitIntersectArguments] and [rtcInitOccludedArguments] for the deets 👑

also also also — to use the argument filter function for some scene, that feature additionally has to get enabled using the RTC_SCENE_FLAG_FILTER_FUNCTION_IN_ARGUMENTS scene flag. so it's giving two switches, not one. see Section [rtcSetSceneFlags] for more 💜

💀 EXIT STATUS 💀

if it fails, an error code gets set, and you can go query it with rtcGetDeviceError. so like, check that if something's acting up 🍓
