Which 3D file formats are recommended for Webgl?
js is your choice, it supports: native json, obj, fbx, gltf, collada, babylon, stl, ply, vrml and many others. Most (if not all?) engines have their own JSON-format and you use offline converters to get your data into the engine format.
How do I use obj files in OpenGL?
You will need to parse the . obj file then (depending on OpenGL version) load the parsed data into array/element_array buffers then use glDraw[Elements/Arrays] to work with in glsl or draw all the vertices using fixed functions.
Is STL or OBJ better for 3D printing?
STL is the de facto standard in consumer-grade 3D printing. In terms of geometry description, OBJ is more capable than STL, as it can describe “real” curves, without the need to approximate them to a series of polygons.
What is 3D model formats?
The basic purpose of a 3D file format is to store information about 3D models as plain text or binary data. In particular, they encode the 3D model’s geometry, appearance, scene, and animations. The geometry of a model describes its shape. By appearance, we mean colors, textures, material type etc.
Can you use OpenGL for any file format?
OpenGL itself holds no relevance to whatever file format you wish to use. If you or your engine can deal with it and get all the relevant information out of it, you can use it. Thanks for contributing an answer to Stack Overflow!
Can a mesh be animating in OpenGL?
Therefore loading a mesh and animating it is something you should take care of, subsequently informing OpenGL what it has to draw. You can however make your life a bit easier by looking for OpenGL based rendering/game engines/scenegraphs out there that already provide the support you desire.
How to create 3D models from real objects?
You can put background images of each orthographic views and then keep on drawing the isometric (3D) as you want to create from 3d models from real objects . Using blender the objects can be converted to .obj wavefront format and can be imported to Opengl.
