kichikuou 31823f5731 ReignEngine: Draw instances in z-order 
To get correct blending effect for overlapped transparent objects.

Nunuhara Cabbage 835679205c Merge pull request #76 from kichikuou/overflow 
Fix integer overflow in audio_mixer.c

kichikuou 88268b084c Fix integer overflow in audio_mixer.c 
This fixes a bug in Toushin Toshi 3 where the audio thread crashes when
battle ended, after exploring the second dungeon for (INT_MAX / 44100)
milliseconds (~= 50 secs).

kichikuou 2370052b54 ReignEngine: Fix bone mapping between model and motion 
Some motion files (e.g. maidsan_ahoge_* and otokomae_*) have wrong bone
IDs, so bone names should be used to look up matching bones in the
model.

However, this does not always work because masokan.POL has multiple
bones with the same name. In that case ID matching must be used.

kichikuou 252f1b5464 Fix out-of-bounds access in MsgSkip HLL

Fix text rendering issue in OpenGL ES
 2022-10-03 21:54:32 -07:00
kichikuou 3f1d76cd9f Fix text rendering issue in OpenGL ES 
This fixes an issue where text is not rendered on Android.

In OpenGL ES3.0, GL_RED is not a valid value for the internalFormat
parameter of glTexImage2D.

kichikuou 803bb1a8a4 ReignEngine: Fix BackCG issues 
- Enable both alpha map and alpha mod, using the new drawing function
  gfx_copy_stretch_blend_amap_alpha().
- Do not draw if `bcg->show` flag is false.
- Do not WARNING() for SetBackCGNum(0) as it's used to unload the CG.

kichikuou 0ff9c5a62c ReignEngine: Add loader for particle effects 
This implements a parser for particle effect definition files (.pae)
and a set of field accessor functions for the RE_ITYPE_PARTICLE_EFFECT
instance type. Rendering of effects is not yet implemented.

kichikuou 06a630ea62 ReignEngine: Implement Fog 
There are two types of fog, linear fog and atmospheric scattering. The
formula for light scattering is incorrect (see the comment in
reign.v.glsl) and therefore not physically correct.

kichikuou d185ae71bf ReignEngine: Implement CalcInstanceHeightDetection 
This is used to compute Y-positions of map objects.

It is called quite often, so this implementation creates and caches a
height map of the instance by (re)using the shader for shadow mapping.

ReignEngine: Fix billboard rendering issue
 2022-07-09 17:22:40 -07:00
kichikuou 5e25dd4000 ReignEngine: Fix billboard rendering issue 
This fixes an issue where billboard objects are not drawn in some
environments.

ReignEngine disables some vertex attributes when drawing billboards, but
AMD's driver doesn't draw anything if any of those attributes are
assigned to attribute index 0.

To avoid this, this explicitly binds "vertex_pos" attribute (which is
always enabled) to index 0.
