| Sliders allow you to adjust the //rotation around the z-axis// and the //tilt of the z-axis//. This ensures that the z-axis always remains aligned upwards. The 3D graphics allow for further [[OperatingGraphics3D|settings]], which then only apply to the current graphic. The example graphic on the left shows immediately how the settings affect the result. | Sliders allow you to adjust the **//rotation around the z-axis//** and the **//inclination of the z-axis//** (tilt).

| The //number of support points// determines how many individual points CGRAPH calculates to create flat graphics. For example, with a setting of 32x32, the two variables required for this then run through loops with 32 values each, so that a total of 1024 values are calculated. | The **//number of sampling points//** determines how many individual points CGRAPH calculates to create flat graphics.

| The graphic also contains a red sphere. This shows how the //transparency// control affects the graphic. The setting does not allow for complete transparency (which would make the sphere invisible). | The graphic also contains a red sphere.

| The //transparency// only applies to the objects created previously. If, for example, two spheres are displayed, the first sphere can be seen behind the second. However, if you look at the image from the perspective of the first sphere, the second sphere is hidden behind it, regardless of the transparency setting. | The **//transparency//** only applies to the objects created previously.

| CGRAPH adds a surface grid to 3D graphics to illustrate the course of the surfaces. This grid can be drawn in a slow version or in a fast, optimised version. The slow version follows exactly the selected fill pattern that was chosen in the graph settings. The fast version uses an optimised grid. | CGRAPH adds a surface grid to 3D graphics to illustrate the course of the surfaces.
