kichikuou 33760da0fa Implement Cursor.Set HLL function 
In Toushin Toshi 3, it is used only to show / hide the mouse cursor.

kichikuou 00d1d01353 ReignEngine: Per-mesh control of drawing order 
Before this, the order of drawing was determined on an instance-by-
instance basis. Instances with even a single transparent material were
drawn after fully opaque instances.

After this, first the opaque meshes in all instances are drawn, and then
the transparent meshes are drawn from the nearest to the farthest.

kichikuou 5f17dafdf8 ReignEngine: Set correct initial value for fog parameters 
This fixes rendering issue of the model viewer in Alice's Mansion.
 2022-11-05 22:17:38 +09:00
kichikuou 581593f9b5 ReignEngine: Support (env) mesh attribute 
If specified, the mesh should be rendered with environment mapping
using the material's COLOR_MAP as a matcap texture.
 2022-11-05 20:56:26 +09:00
kichikuou 241f631d9d ReignEngine: Set loop frame range for particle effects 
Without this, update_motion cannot calculate current_frame correctly
when the effect is used with RE_MOTION_STATE_LOOP state.
 2022-11-05 20:56:26 +09:00
kichikuou 814ebb7d3d ReignEngine: Support (sprite) material attribute 
If specified, alpha test is used instead of alpha blend.
 2022-11-05 20:56:25 +09:00
kichikuou 1a9a2e9753 ReignEngine: Support (nolighting) mesh attribute 
In ReignEngine, the mesh name field may contain keywords that change
rendering behavior. The "(nolighting)" keyword disables lighting and
fog.
 2022-11-05 20:56:25 +09:00
kichikuou 31823f5731 ReignEngine: Draw instances in z-order 
To get correct blending effect for overlapped transparent objects.
 2022-11-05 20:56:25 +09:00
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).
 2022-10-22 10:23:22 +09:00
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.
 2022-10-10 14:20:20 +09:00
kichikuou 252f1b5464 Fix out-of-bounds access in MsgSkip HLL 
Toushin Toshi 3 calls MsgSkip.{Get,Set}Flag with msgnum = -1.
 2022-10-10 14:20:20 +09:00
kichikuou 5c288f87e5 Implement EFFECT_TV_SWITCH_OFF 
Used in Toushin Toshi 3.
 2022-10-10 14:20:20 +09:00
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.

This completes the implementation of the particle effect system, except
for the camera quake effect.
 2022-09-25 10:39:37 +09:00
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 c30225d535 ReignEngine: Bind all vertex attributes to fixed locations 
So that model_load() doesn't have to depend on RE_renderer.
 2022-09-11 14:39:37 +09:00
kichikuou 2ceb727a66 ReignEngine: Instances with draw=false should not cast shadows 2022-09-11 14:35:50 +09:00
kichikuou 7bffaeffe6 ReignEngine: Fix projection matrix calculation 
Now it makes the same angle of view as the original ReignEngine.
 2022-09-11 14:33:43 +09:00
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.
 2022-09-04 10:17:03 +09:00
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.
 2022-08-06 09:38:48 +09:00
Nunuhara Cabbage 3e536af09a Implement DG_ADD, DG_EXIST, DG_ERASE 2022-08-02 18:16:16 -07:00
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.

kichikuou 233b2a4f20 ReignEngine: Implement shadow mapping 2022-07-24 16:01:16 +09:00
kichikuou b0e540e67b gfx: Expose low level shader loading function

uniform variable configurations.

kichikuou 2918a6310c ReignEngine: Remove hard limit on number of instances 
Some maps in Toushin Toshi 3 have more than 32 instances.
 2022-07-23 21:41:41 +09:00
kichikuou fc81d0ec4e ReignEngine: Do not ignore BuildModel() with elapsed time 0 
It isn't no-op, because instance motion may be changed by
SetInstanceMotionFrame().
 2022-07-23 21:23:13 +09:00
kichikuou e7c9410df4 ReignEngine: Implement two functions 
GetInstanceBoneIndex and TransInstanceLocalPosToWorldPosByBone.
 2022-07-18 13:01:49 +09:00
kichikuou 3343efbcb9 Implement ReignEngine.BuildModel 
Instance motions are updated with this function.

vertex buffer.

Nunuhara Cabbage 2e23554162 Implement SACT2.Joypad_GetAnalogStickStatus 2022-07-09 17:35:07 -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.

kichikuou b42032c9f8 ReignEngine: Implement basic lighting 
This implements a Phong shading with ambient, diffuse and specular
components, using up to three directional lights and one specular light.

The light calculation is made to match the "high quality" 3D mode of
Toushin Toshi 3.
