asarium 8f88801646 Add dynamic action programming system
This system adds the code necessary for letting content creators specify
complex events by specifying a simple, program-like sequence of
operations that will be executed by the engine when a certain event is
triggered.

asarium e8e549ff08 Add scripting API for tracing custom code
This can be used by Lua code to trace the runtime of their code in the
same way the engine already is capable of doing for most in-mission and
mission loading code.

Also adds some tracing scopes to the libRocket code

asarium 2e0253e301 Add a mechanism for batching line draw calls
The previous version used NanoVG which caused quite a serious FPS drop.
This adds a buffer batching class which groups line drawing operations
together and submits them to the GPU with a single draw call.

asarium acc018507b Pack vertex and index data into one buffer
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.

asarium 99f69c903e Add screen space decal rendering system
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.

asarium abbef793fc Add tracing scopes for HUD rendering
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.

asarium c6975fda3c Use uniform buffer blocks for passing uniform data to shaders
This uses UBOs for building a buffer object of uniform data before
using that data to draw objects. This should reduce the CPU overhead by
reducing the amount of glUniform calls required for executing a single
draw call. This is especially useful if rendering is limited by the CPU
which should help performance for people with slower CPUs.

This fixes #910.

MageKing17 f6b1eaa846 Fix duplicate tracing/profiling category.
Cutscene audio decoding was accidentally named "FFmpeg decode video", causing some minor problems in the profiling code (because the same name is used for actual video decoding, resulting in an assertion firing).

asarium abdef9f7b0 Add tracing scopes to the mission load code
This makes it easier to determine what takes the most time while loading
the mission (loading models) and how we could optimize that load time
(optimize model loading).

This is not a bug fix but it also shouldn't cause any regressions since
there are no actual code changes so this could be merged before the
release of 3.8.

asarium b9413a2639 Improve handling of environment redrawing
This should make sure that the environment map is only redrawn if
necessary. In my case that should improve frame times by around 1ms for
the normal case when the environment map doesn't need to be redrawn.

Fabian Woltermann b3a8824d68 Adds more trace scopes to get a better look at the internals of render_frame 2017-02-02 15:07:43 +01:00
asarium d64196eff0 Refactor tracing subsystem
The new design is centered around the Event Trace JSON format but it
should still be possible to adapt it for other profiling tools. The old
profiling system has been removed.
