This is the maximum number of bones in a model for Rance Quest
(pasuteru_full.POL).
Now bone transform matrices are stored in a uniform buffer object,
because its size exceeds GL_MAX_VERTEX_UNIFORM_COMPONENTS in iOS Safari.
- Use glm_look_anyup() to avoid singularities when the shadow light
direction is parallel to the up vector
- Fix bounding sphere calculation when there are multiple shadow casters
TapirEngine is the 3D rendering engine used in RanceQuest.
This implements the minimum functionality that is needed to render the
first battle scene. The lighting is still incorrect.
This fixes an issue where height detection fails due to gaps in
suspension bridge planks.
If the depth map has no value for the given point, return the average
of 4 neighbors.
Now parsed particle-effect definitions are cached in a hash map in the
plugin object. To make it possible, static part of `struct
particle_effect` and `struct particle_object` are factored out to
`struct pae` and `struct pae_object` respectively.
It visualizes the bounding sphere of the instance. Although it is only
called from dead code in Toushin Toshi 3, it's useful for debugging
shadow mapping.
This fixes broken shadow rendering e.g. when Nacht climbs a ladder.
Now update_bones() calculates the instance's bounding sphere which
is the minimum sphere containing the AABB of current bone coordinates.
This corresponds to the sphere that is displayed when calling
SetInstanceDebugDrawShadowVolume on the original ReignEngine.dll.
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.
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.
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.
- 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.
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.
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.
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.
