ReignEngine improvements

kichikuou 8c72c5b5e0 ReignEngine: Normalize vectors after applying normal_transform 
normal_transform can be non-orthogonal, so after transforming with it
direction vectors must be normalized.

This fixes a bug where President Garter is rendered too specular.

kichikuou 9a6553f215 ReignEngine: Fix glTexImage2D arguments for shadow renderer 
GL_DEPTH_COMPONENT is not a valid value for internalFormat in OpenGL ES.

kichikuou 3ef252c68b ReignEngine: Improve z-sorting 
This fixes billboard rendering issue in some dungeons.

* For polygon models, use its AABB's center coordinates.
* Consider the camera angle, i.e. sort by view-space Z-coordinate
  instead of world-space Z-coordinate.

kichikuou 6cc0bd7cb4 ReignEngine: Implement (both) mesh attribute 
I'm not sure what it means exactly, but at least it disables shadow
drawing (but does not disable shadow casting).

kichikuou b79eb9ccea ReignEngine: Do not WARNING() on SetBackCGName("") 
It just unloads current CG.
 2022-12-10 11:34:34 +09:00
kichikuou 408f35f4ec Fix ReignEngine.SetInstanceScaleZ 2022-12-10 11:26:14 +09:00
kichikuou 5b9e7ac7e4 ReignEngine: Correctly mark transparent materials 
There are two types of transparent materials: materials that have an
alpha map and materials that have a color map with an alpha channel.
This change makes the latter to be considered transparent.
 2022-12-10 11:25:42 +09:00
kichikuou c5b0122d72 ReignEngine: Use glDepthFunc(GL_LEQUAL) when drawing billboards 
So that multiple billboards overlapping on a plane are rendered
correctly.

Nunuhara Cabbage 7aaa19404c Merge pull request #82 from kichikuou/mmap 
Do not use ARCHIVE_MMAP on 32-bit systems
 2022-11-26 20:34:01 -08:00
kichikuou 6efa31454d Do not use ARCHIVE_MMAP on 32-bit systems 
Some games have assets that are too large to mmap everything on a 32-bit
address space. For example, TT3 has a total of 2.82GB of assets, which
is too large for the 3GB address space limit of 32-bit Linux. On Android
it's even stricter and mmaps of hundreds of MB can fail.

ReignEngine: Implement {Get,Set}InstanceDrawType
 2022-11-24 19:16:50 -08:00
kichikuou 638de2057a font_freetype: Consider glyph information for horizontal positioning 
When creating a block-sized texture from a glyph, use the bitmap_left
field of FT_GlyphSlot instead of just centering it horizontally.

This improves positioning of punctuation marks in Japanese text.
 2022-11-20 12:02:18 +09:00
kichikuou 28f95bfe38 ReignEngine: Implement {Get,Set}InstanceDrawType 
Billboards of draw type 1 are drawn with additive blending.

Nunuhara Cabbage c296ca1682 Merge pull request #79 from kichikuou/cursor 
Implement Cursor.Set HLL function
 2022-11-19 08:32:59 -08:00
kichikuou 33760da0fa Implement Cursor.Set HLL function 
In Toushin Toshi 3, it is used only to show / hide the mouse cursor.

Nunuhara Cabbage 36d2216e66 Merge pull request #78 from kichikuou/reign 
ReignEngine: Per-mesh control of drawing order
 2022-11-16 20:20:56 -08:00
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.

ReignEngine improvements
 2022-11-09 16:37:53 -08:00
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.

Nunuhara Cabbage 835679205c Merge pull request #76 from kichikuou/overflow 
Fix integer overflow in audio_mixer.c
 2022-10-22 09:30:22 -07:00
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
Nunuhara Cabbage 76aba9cd6b Merge pull request #75 from kichikuou/tt3 
Fixes / improvements for Toushin Toshi 3
 2022-10-12 20:05:20 -07:00
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.

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.
