* Add support for u8 bone indicies when loading glTF
* Fix segfault for glTF animations not keyframed at 0
When loading glTF animations we lerp between keyframes, and previously
assume that if the frame we are considering has a later keyframe, there
must be a previous keyframe. This is not true if the animation's first
keyframe is some time into the animation. In this case we now
effectively clamp to that first keyframe for any time prior to it.
* Respect parent bones tranform when loading glTF animations
We previously assumed that when loading glTF animations, the bones were
ordered with those higher up the skeleton tree (i.e. closer to the root)
came first in the list of nodes. This may not be true, so now we
repeatedly loop, preparing each level of the skeleton tree one after the
other, starting at the root level. This ensures that any parent
transforms are applied before transforming any child bones.
We also ensure that we have forced the loading of animation data before
attempting to interpolate to generate the animation frames for use
later, without this no animations are applied.
Finally we remove the check that assumed the first node in the nodes
list is the root, and use an invalid index value as the sentinal value
for when a node has no parent. Previously this was 0, which made
distinguishing between root nodes and children of the first node
impossible.
Actually, it seems more logical that rlgl takes care of OpenGL data than the models module...
Also, models module loaded vertex data is unloaded by models module.
* Added example for gltf animation and split some functions for loading model animations into IQM and GLTF similar to how models are being loaded.
* Removed wrongly duplicated function
* Bone loading for gltf model (not working at this point)
* Loading info about vertex to joint connection but animation is still not working
* Skeleton and pose is correctly loaded. Need to communicate about interpolation in GLTF
* The model almost looks like a real person on animation.
* Fixed model loading with bones.
Also updated license info on the model.
* Cleaned up some code and updated examples.
* Fix identation issues
* Fix identation issues
* Fix identation issues
Pefixing/Suffixing some data type identifier in the variables is not a convention used in raylib, just reviewed it for consistency...
Still, I kept the *Rec suffix in some functions.
This redesign allows more flexibility when creating RenderTexture and a simplification (and hopefully removal) of `GenTexture*()` functions, that should not belong to this model but the user code, due to the use of custom shaders.
Also, this new API opens the door for a possible GBuffers type and advance rendering possibilities...
Some functions of the API have been also simplified or even removed.
rlgl module can be used as an standalone library, so, a version for the library has been added: v3.1.0, matching current raylib version.
Most warning were related to types conversion (casting required) and unsigned/signed types comparisons.
Added preprocessor directives (_CRT_SECURE_NO_DEPRECATE; _CRT_NONSTDC_NO_DEPRECATE) to avoid warnings about unsafe functions, those functions are safe while used properly and recommended alternatives are MS only.
Some external libraries still generate warnings.
There are multiple #define values around raylib, usually not exposed for redefinition, just reviewed all of them to allow users redefining them on compile time if required.
Also, multiple #define have been renamed and commented.
Actually this function is useless and potentially dangerous, internally, a shallow copy of data was done. Same could be accomplished accesing image.data directly.
Errores fixes:
models.c,2843 Either the condition 'fileData!=NULL' is redundant or there is possible null pointer dereference: fileData.
raudio.c,805, 806, 807, 808, %d in format string (no. 2) requires 'int' but the argument type is 'unsigned int'.
* 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
