Ok rock stars, here is our Flex design wheelchair animation in Daz3D. With a few quick steps you can have fun creating your own wheelchair animation in Daz3D at home for free. Download a free version of Daz 3D from their website. Previously I showed how to import 3D models and figures, set colors, textures, clothing, pose the figures and so on. Now let’s have some 3D anim movie fun.
Wheelchair Wheel Rotation
To setup your wheelchair wheel rotation open Daz3D and click the Pose & Animate tab. 1) Import your wheels to the zero point. 2) Set X Rotate to 720. 3) Set Y Translate to 31. 4) On the timeline set 91 frames, a range of 0 to 90, and drop the frames per second (FPS) to 20. 5) On frame 90 set Z Translate to -389.36. Render to see if your wheelchair wheel rotation is correct and matches the distance.
It might be worth explaining how I calculated wheel rotation and distance. 2 PI R equals the circumference of a circle. Imagine wrapping a string around the tyre then laying it out flat, we want to know that measurement to sync the wheel rotation to distance. PI is 3.14 and R (radius) is 31. So 3.14 x 31 x 2 = 194.68 for one full wheel rotation. Times 2 again for two wheel rotations and we get 389.36.
Posing Disabled Wheelchair Model
Now the wheelchair animation is looking good we start posing disabled wheelchair model Michael. Sit him in our flex wheelchair at frame zero and on frame 90 set Z Translate to -389.36. Then add key-frames and adjust his chest, arms, hands etc to give the illusion he’s pushing the wheelchair. Take a few renders going back and tweaking to achieve a realistic motion. Here’s our paraplegic hunk Michael in motion.
Sweet, all we do now is set a scene add a few lights and drop in a background. Indoor lighting can be a bit tricky in Daz3D so I won’t bore you with all that here. Just know in Daz3D you need raytracing on at least one light to get a realistic shadow effect. Here we have the sunlight (distant light) coming through the window and four down lights (spotlights) all set with raytracing on.
And with that I’m off to watch The Lorax.
