Wrong Bone Rotation in Assimp

阅读更多关于 Wrong Bone Rotation in Assimp

问题 Recently I am working on some way to transform a given bone (rotate by some angle ) using Assimp in visual Studio C++. I read at many sites procedure to do this and still I am not able to find error with multiple trials for matrix multiplication orders. What I'm doing is given a model I firstly find the perVertexBone data and then I find bone locations prior any transformation and then represent all vertices in Model using linear weight assignment with bones using perVertexBone data

How to slow down opengl animation read from BVH files?

阅读更多关于 How to slow down opengl animation read from BVH files?

问题 Using GLFW3, I currently made a bvh file parser which reads the file in and converts it to a human model I made in opengl. However, whenever I launch it, the movement is so fast that the animation cannot be seen in the eye. So I want to tone the animation speed a little down. Here is my render loop while (!glfwWindowShouldClose(window)) { // per-frame time logic // -------------------- float currentFrame = glfwGetTime(); deltaTime = currentFrame - lastFrame; lastFrame = currentFrame; // input

How to parse a bvh file to a skeleton model made in OpenGL?

问题 I'm trying to parse the bvh data to my skeleton I already developed with OpenGL. There is one thing regarding data parsing I got curious about though. Bvh data has two parts, which are HIERARCHY and MOTION. HIERARCHY specifies the tree structure and the OFFSET data, which is used to infer the length of the parent bone. MOTION specifies the position of the root bone and the joint configurations of every bone. I already made my model with the bones that were mentioned in HIERARCHY. I made my

Model with bones animation (blender export) animating incorrectly in three.js

I am currently working on skeletal animation tests in three.js. I have a simple model which animates just fine in blender. Basically it consists of three stacked, bending cubes. When I export the blender file to the three.js using the blender export plugin with Blender V2.64, the animation in the webGl context appears different as if the skinweighting is wrong. WebGL-Demo: http://rainbowrangers.de/threejs/animation_test01/ Blender-File: http://rainbowrangers.de/threejs/animation_test01/model/animation_test01.blend What do I have to do to get the correct result in three.js? I am the person you
