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.
All transformations are now handled by shaders so there is nothing
special going on in the graphics API specific code anymore. Since model
uniform buffers require access to these matrices I moved the matrix
handling out of the graphics API code.
The updated values for the distortion map were rendered too close to the
edge of the screen so they were clipped which meant that there was no
distortion data available. This fixes that by moving the rendered
primitives farther away from the edge. I'm not sure why this worked in
3.7.4, maybe the fixed function rendering used some slightly different
matrix.
I also don't know why this wouldn't work consistently across GPU vendors
but maybe the rasterization rules vary a bit across drivers.
This fixes#1307.
If the object number is set for the render info the renderer uses the
instance information of that object to render the model. That is not
correct for the lab since the instance data is handled by the lab code
in that case.
This fixes#643.
This fixes a few of the bad design descisions of previous shader
iterations. This uses a dedicated class for managing the resources and
uniform locations of a shader program.
Uniforms are also stored in this object which makes a lot more sense
than storing them in the OpenGL state where they had to be reset every
time a new shader was used.
There are still a lot of possible enhancments to make, e.g. by using
uniform blocks and buffers instead of standard uniforms which would make
uniform location handling easier.
Another optimization that I will investigate is reducing the amount or
different compiled shaders by turning some of the current compile-time
defines into bool uniforms.
This introduces a new mechanism for handling bit flags. Instead of using an int (or two, or three) to write bits into, this uses the std::bitset in a wrapper class that accepts an enum class as input. This means that certain classes of errors we've had a few of in the engine, where a coder used the wrong set of flags or checked them against the wrong variable (SF_STEALTH vs SIF_STEALTH, for example) can now be detected at a compiler level rather than not at all.
Fix silly issue preventing getFrame() from working
Remove infinite loop when calculating frame num
Convert more animations to use new frame calc function
i.e. apngs (pre)loaded into bmpman slots
handles apng variable frame delays
Includes new lua function (getFrames) to find the current frame for
apngs. Also uses new function to correctly display apngs for mission
loading animations, ship thrusters & engine glows.
Replaces calls to double-precision floating point trig functions with
calls to single-precision floating point trig functions as follows:
cos() -> cosf()
sin() -> sinf()
tan() -> tanf()
acos() -> acosf()
asin() -> asinf()
atan() -> atanf()
This allows the compiler to avoid generating unnecessary instructions
that convert a float to a double and then a double back to a float.
