This changes the model loading code such that all index and vertex data
is packed in a single GPU buffer for each data type (index and vertex
data are still in separate buffers). This reduces the amount of buffer
rebinding needed when rendering a scene which will reduce the CPU
overhead. Furthermore, this opens up possibilities of future
improvements for which it is beneficial if all data is in the same
buffer (e.g. MultiDrawIndirect rendering).
To manage where to put the data in the GPU buffer I implemented a
custom HeapAllocator which manages where data can be put. It uses a very
primitive first-fit algorithm but that is sufficient for this usage
type. This does add quite a lot of overhead while allocating GPU model
data (I did some tracing and some allocation calls took as long as
130ms).
This fixes#1457.
This allows to render screen space decals into the deferred lighting
buffers no matter how complex the underlying geometry is.
Currently there is only limited support for using this in the engine.
Only weapon impact decals are supported at the moment for testing
purposes.
When Unicode_text_mode was false, unicode::num_codepoints() would return (the size_t equivalent of) a negative number, because it was checking the distance from end to start instead of the distance from start to end.
There are a few new warnings in GCC7 so this makes sure that no warning
gets missed by our CI setup. The new configuration should be updated to
the newest GCC version whenever possible.
The crash described in #1561 was caused by a NULL ai profile. The
profile was not set because the lab system already had a loaded ship
object (see line 2230). These changes make sure that the loaded ship
object is deleted before closing the lab system which ensures that the
ai profile is set the next time the lab is initialized.
This fixes#1561.
While debugging a performance issue reported on Discord I noticed that
the HUD rendering code does not have any tracing scopes. This adds a few
tracing scopes to that code to make performance debugging a bit easier.
Previously the campaign room caused a heap-use-after-free error
(detected by AddressSanitizer) when loading the campaign failed two
times. This fixes the error by resetting the text pointers to their
default values when freeing the campaign list data.
This should be the correct way to set the combined depth/stencil buffer.
This has not been tested yet since I do not have a GPU which causes
these issues.
This fixes#1555.
The normally faster version that was used before misbehaved if that
texture unit already used the specified texture object which caused the
glTexSubImage3D to cause out of bounds issues some times.
This fixes#1554.
