* Update GLTF support to include loading color for albdeo (saved in the color value of the materialmap), support occlussion and emmission maps.. as well as some quality of life updates.
* clean up to use single image
Just for clarification, no plans to remove libc dependency, just did some code analysis to see how much raylib depend on stardard C library. My conclusions:
- stdlib.h: primary dependency is for malloc() and free()
- stdio.h: primary dependency is for FILE access, maybe it could go through a custom ABI?
- string.h: just around 8 functions required
- math.h: just around 8 functions required
- others: 1-2 functions required for some other headers
* Initial commit of addition for GLTF materials.. should support loading more than just albedo map.
* Clean up
* fixed seg faults and leaks
* temp don't overwrite defuse colour when rendering
* undid something dumb!
* correctly mixed diffuse map color when rendering to preserve not overwrite it
- Mesh, Shader, Material structs have been reviewed to minimize size when passed by value, all required code has been reviewed.
- GetCollisionRayModel() reviewed to avoid pointer, not required because model is not modified inside the function
- UnloadMesh() reviewed, pointer not required
- CheckCollisionRay*() parameters name reviewed
* Fix loading multiple animations from .iqm file
* Fix memory leak in models_animation example
* Added export instructions to the animation example
* use raylib free
* include <stdlib.h> to appease the travis CI gods
* replace tabs with spaces
Square root calls are computationally expensive. In this case, they can be avoided. Instead of checking distance<RadA+RadB, check distance squared against (RadA+RadB) squared. The dot product of Vector3Subtract(B,A) with itself gives distance squared, so I used this code instead of an element-by-element computation of distance squared. The only downside is that your geometric code is very readable, whereas this is less so.
Users can define their custom memory management macros.
NOTE: Most external libraries support custom macros in the same way, raylib should redefine those macros to raylib ones, to unify custom memory loading. That redefinition is only implemented as example for stb_image.h in [textures] module.
Issue was related to vertex tangent attibutes not uploaded to GPU, a quick solution was implemented for new vertex attributes loading for already existing meshes... I don't like it specially but it will work for now.
This is quite a big change, Model struct has been redesigned to support multiple meshes and multiple materials, most 3d fileformats contain multiple meshes and reference multiple materials.
Consequently, multiple functions have been reviewed.
LoadOBJ(), LoadIQM(), LoadGLFT() now return a Model.
Current LoadOBJ() is not valid anymore, actually, tinyobj_loader_c library is considered for replacement.
- Added Vector3OrthoNormalize() to raymath.h - not sure if it is correct
- Implemented MeshBinormals() - Mesh struct has not a place for them...
- Updated model_material_pbr example - tested but not working on my GPU
(old Intel HD), actually, it never worked on it...
That way, a user needs only to touch a single file to configure what
features raylib is built with.
Include guards are left out intentionally, because config.h should only
be included in source files, not headers.
Later on, config.h can also define the raylib version (#461).
