#Model

SafiEngine::Model loads and renders 3D models from glTF/GLB files using modern OpenGL (VAOs + shaders).

Header: Core/include/Core/Model.h

#MeshData

struct MeshData {
  std::vector<float> positions;   // 3 floats per vertex
  std::vector<float> normals;     // 3 floats per vertex
  std::vector<float> texcoords;   // 2 floats per vertex
  std::vector<uint32_t> indices;
};

A plain data struct holding raw vertex data for constructing a Model programmatically. Used internally by ProceduralMesh to generate primitive shapes.

#Methods

#Load

bool Load(const std::string &path)

Loads a .glb (binary glTF) file. For each mesh primitive, it creates a VAO and extracts:

• POSITION: vertex positions → VBO, vertex attrib location 0
• NORMAL: vertex normals → VBO, vertex attrib location 1
• TEXCOORD_0: texture coordinates → VBO, vertex attrib location 2
• Indices: uploaded to an EBO (supports u8, u16, u32)
• Material: PBR base color factor and base color texture

Returns true on success, false on failure (prints error to stderr).

#GetCenter

glm::vec3 GetCenter() const

Returns the geometric center of the model's bounding box, computed from glTF accessor min/max values during Load(). The render system uses this to rotate entities around their visual center rather than the model origin.

#Draw

void Draw(const Shader &shader) const

Renders all loaded meshes using the provided shader:

• Sets uBaseColor uniform per mesh from the material's base color factor
• Sets uHasTexture and binds the base color texture to sampler uTexture
• Binds the mesh VAO and calls glDrawElements

#CreateFromMeshData

static std::shared_ptr<Model> CreateFromMeshData(const MeshData &data);

Creates a Model from raw vertex data without loading any file. This is used internally by ProceduralMesh to build primitive shapes, but can also be used directly to create custom geometry.

Returns a shared_ptr<Model> ready for rendering, or nullptr on failure.
