RuntimeError: memory access out of bounds

RuntimeError: memory access out of bounds can occur if there is not enough heap memory. To increase the heap size, set -cheerp-linear-heap-size=<value> to a larger value (in MB, default is 1).

Passing data to WebGL uniform* APIs

uniform* APIs and, more in general, WebGL APIs which expects buffer requires typed arrays of a suitable type.

If you have data stored in a C/C++ array or std::vector or any other contiguous memory storage, you can use the cheerp::MakeTypedArray to convert the data into a JS typed array object. Please note that the conversion happens without copying, so it’s very efficient.
