Is the Y or Z axis up?
The standard orientation, where the xy-plane is horizontal and the z-axis points up (and the x- and the y-axis form a positively oriented two-dimensional coordinate system in the xy-plane if observed from above the xy-plane) is called right-handed or positive.
Is blender Z-up or Y-up?
Blender uses the right hand coordinate system with the Z axis pointing upwards. This is common with the coordinate systems used by most common 3D CAD packages.
Is y-axis vertical in 3D?
Some 3D tools are Y-Up, which means the Y axis is a vertical line; while the others are Z-Up, means the Z axis is a vertical line.
What is the coordinate rule for rotations?
Rules of Rotation The general rule for rotation of an object 90 degrees is (x, y) ——–> (-y, x). You can use this rule to rotate a pre-image by taking the points of each vertex, translating them according to the rule, and drawing the image.

Can You translate a 4×4 matrix to a Y-up coordinate system?
Can anyone translate the generic 4×4 matrix below from a Z-Up coordinate system to a Y-Up Coordinate System? If the geometry is exported as is from the Z Up Environment (you are not flipping the YZ in your settings), you can import it into THREEjs and correct the YZ Discrepancy with this matrix ( link) :
What’s the correct way to rotate y and Z?
Try this yourself, swap the y and z, and reorient the axis so that x points right and y points up. You will see that z points the opposite direction from its original (away from the screen). The proper way is to rotate around the x-axis, which is swap y and z, and then invert the sign of the final z.
What’s the difference between Y-up and Z-Up 3D tools?
Some 3D tools are Y-Up, which means the Yaxis is a vertical line; while the others are Z-Up, means the Zaxis is a vertical line. 3D Tools iClone
