kichikuou fc81d0ec4e ReignEngine: Do not ignore BuildModel() with elapsed time 0 
It isn't no-op, because instance motion may be changed by
SetInstanceMotionFrame().

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.

ReignEngine: Implement basic lighting
 2022-07-09 08:28:34 -07:00
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.

Nunuhara Cabbage 9f42ee379d Improve performance of vm_image_to_json 
Use a callback-based function to create the heap JSON array. This avoids
the O(n) insertion time of cJSON_AddItemToArray.

Nunuhara Cabbage 3a40542aab parts: fix bug with INT_MIN in numeral object 
Use 64-bit integer to avoid overflow when creating numeral for INT_MIN.
 2022-06-25 09:22:11 -07:00
Nunuhara Cabbage 841947d544 Fix delegate memory management and FT_ASSIGNS 
Each delegate call needs to copy its arguments so that they aren't
double-freed by the next call.

Also fix a bug in FT_ASSIGNS where -1 was returned for non-existant
functions instead of 0.

Nunuhara Cabbage fc42c42ef5 parts: refactor parent-child handling 
Parent-child relationships are established by the UpdateComponent
function. Parts_SetParentPartsNumber does not establish the relationship
(and it does not create the parent object if it does not exist yet).

Render params are now computed recursively on children when they are set
on the parent (instead of recomputing them every time a child parts is
rendered).
 2022-06-24 17:54:25 -07:00
Nunuhara Cabbage 8ee136b287 parts: various fixes and improvements 
* SetAddColor and SetMultiplyColor implemented
* additive draw filter implemented
* GetPartsUpperLeftPos{X,Y} implemented
* various parameters are now applied from parent to child parts
* misc. bug fixes

The first dungeon screen in Rance 01 now renders correctly.

Nunuhara Cabbage 25695c3e86 parts: implement GUIEngine numerals 
Implement Parts_SetNumeralLinedCGNumberWidthWidthList and
Parts_SetNumeralLength.

Also fix bugs where changing numeral properties would not update the
texture until the number was reset.
 2022-06-18 10:53:43 -07:00
Nunuhara Cabbage e1872edb5a parts: fix render order of child parts 
The parent's z-value determines the render order of its children.

Alicesoft's implementation of this is a bit weird. The render order only
changes when the parent's visibility is toggled (via Parts_SetShow), NOT
when the parent is set on a child or the parent's z-value changes.

I have chosen to implement this so that the render order is always based
on the current parent/child z-values.

This fixes some bugs in Rance 01.

screen).
