Ever wondering if you can have your own art gallery? In VRMath2, you can create your own gallery and invite friends to enjoy a virtual walk through. Click to read more ...
Do you know that every 3D virtual world created in VRMath2 can be viewed in Cardboard VR with a mobile phone (e.g., iPhone)? Click to find out more....
VRMath2 Editor is an online application for building 3D virtual worlds. The 3D virtual worlds can be shared easily in VRMath2 website. Click to read more ...
VRMath2 is an online community for learning mathematics. Its applications involve fields of science, technology, engineering and mathematics (STEM). Its learning philosophy is learning by constructing meaningful artefacts (building 3D virtual reality microworlds). Click here to read more...
This is my first and simple construction of a molecule. I chose to do Methane (CH4), one atom of carbon and four atoms of hydrogen, because it takes the shape of a tetrahedron. In this blog, I used a different...
It has been a while, a long while that I do not have time blogging. It feels good when I put down work and write a blog. In fact, it did not take long to do this coffee table at all.
This is my fourth take on...
The real advantage of gear modelling in 3d is that gears in a mesh do not have to parallel each other. It is posible to demonstrate how gears can transfer rotation (and forces) to orientations other than the...
The dragon curve is a fractal which is defined by replacing a segment of the curve with a (smaller) version of itself.
For better rendering performance, open scene in new window by...
Getting gears to appear smooth by explicitly assigning indices to the generated facets got me thinking in more detail of how to accomplish this result in general, for any facets drawn in face mode by turtle graphics.
The real advantage of gear modelling in 3d is that gears in a mesh do not have to parallel each other. It is posible to demonstrate how gears can transfer rotation (and forces) to orientations other than the driving gear. This kind of transfer is possible by use of helical gears.
As an update to the 2d involute (curved teeth) gears, I modified the program to produce 3d (extruded) gears. This required a change in drawing tactics.
Finally, not perfect at all but working gear set in 3D. Thanks to asplech's blog about involute gear and this Spur Gear document, I finally get to know better about these cogged wheels.
