daographics's Issues

Enhancement: take a look at Blend2D and AsmJIT

The following popped in my mind when I saw the comment rendering cubic bezier curves in the source code. There are running projects for low-level graphical pipeline optimization and high-performance vector graphics computation on CPU.

http://kobalicek.com/cpp.html
https://github.com/kobalicek/asmjit
https://github.com/blend2d

Both are written in C++ and the developer is really eager to work on them already few years. The performance and quality results are quite stunning. It might be worth taking a look at or even start using it. Btw once these projects get reasonably stable, he'll finally continue his work on SVG rendering library and a multiplatform GUI library (see http://kobalicek.com/ for more information).

Few typos

In void DaoxRenderer_DrawTask( DaoxRenderer *self, DaoxDrawTask *drawtask ), the variable j is only declared, but not used.

The declaration of void DaoxPathStyle_Convert( DaoxPathStyle *self, int buffer[DAOX_MAX_DASH+4] ), should be changed to void DaoxPathStyle_Convert( DaoxPathStyle *self, int buffer[DAOX_MAX_DASH+5] ) as everywhere else 5 is used for buffer size increase (in the function body, but also in the caller functions).

In source/dao_animation.c:53, the variables scale, rotate, and translate are unused.

In DaoxParticle* DaoxEmitter_AddParticle(...), there is

...
if( lifeSpan < 0.5*self->lifeSpan ) lifeSpan = 0.5*self->lifeSpan;
if( lifeSpan < 2.0*self->lifeSpan ) lifeSpan = 2.0*self->lifeSpan;
...

but it's semantically the same as the following (saving few instructions ;)):

...
if( lifeSpan < 2.0*self->lifeSpan ) lifeSpan = 2.0*self->lifeSpan;
...

or there is a typo and the line if( lifeSpan < 2.0*self->lifeSpan ) lifeSpan = 2.0*self->lifeSpan; should become if( lifeSpan > 2.0*self->lifeSpan ) lifeSpan = 2.0*self->lifeSpan;.

Outlook on associated technologies

Just to make a public note.

OpenSL ES (Open Sound Library for Embedded Systems)
