Visualiser with FP64 `x`/`y`/`z` runtime error #1217

Open ptheywood opened 1 month ago

ptheywood commented 1 month ago

Using doubple precision (64 bit) floating point values for X/Y/Z (and presumably glm position) types results in an error at runtime in ModelVis.cpp. 

Agent 'agent' has not had x, y or z variables set, agent requires location to render, in ModelVis::activate()

This might actually need a change in the vis repo, where core_text_buffers is set, but the error is thrown from ModelVis.cpp in this repo.

Yeah, will need implementing on the visualiser side. May need to do some type conversion, not too sure about double precision floats in shader texture buffers.
