Hope you have enjoyed the tutorial on 2D Coordinates
In this tutorial, the concept of 3D coordinates is explained.
when we talk about 2D objects like a board or a wall, we use 2 dimensions.
For example, we say that a board is 10 feet wide and 2 feet high.
But, when we talk about 3D objects like a swimming_pool or a box, we will use 3 dimensions.
For example, we say that a swimming_pool is 5 feet deep, 10 feet wide and 20 feet long.
Apart from the x and y dimensions, a 3D point will also have one more dimension... Z.
In the following flash control, these 3 dimensions are visualized.
You can notice that the 3 sliders have 3 different colors.
If you move the red slider, the RED PLANE will move along the X-axis.
If you move the green slider, the GREEN LINE will move on the red plane, along the Y-axis.
If you move the blue slider, the BLUE POINT will move on the green line, along the Z-axis.
Feel free to drag the 3 sliders and see how the diagram gets modified accordingly.
