# Geoservant 3D | Create solid Geometry in 3D

Übersicht aller Rechner

Using the Geoservant you can create geometric shapes from simple text. For example, input "cube(0|0|0 5)" and you get a cube drawn in the origin of ordinates with an edge length of 5. All available drawing objects are listed below.

### Input:

Enter one geometric object per line.

### Tips on Geometric Inputs

1. Colors: Add the in the end of the line in brackets, for example: sphere(3|3|1 2){F00}
2. Coordinate Planes: You can show them by adding the line , remove the ones you do not need. Add # behind for grids.
3. Rotation: Cuboid, cube, text, cylinder can be rotated in x-y-z-direction, simply add the angles (in degrees) in square brackets in the end. Example:
4. Animation: Values can be changed gradually. Click on any number value, hold the CTRL ATL SHIFT keys and press cursors for 0.1 steps and for 1.0 steps.
5. To create a cone, choose a and set rt (radius of top surface) to value 0. For example: cylinder(2|2|0 2|0|4|200)
6. To create a hemisphere or parts of a sphere, use the extended syntax for spheres: sphere(x|y|z radius, phiStart, phiLength, thetaStart, thetaLength) Let us explain the different values: phiStart is the horizontal starting angle, phiLength is the horizontal sweep angle, thetaStart is the vertical starting angle and thetaLength is the vertical sweep angle. Here is an example of a hemisphere: sphere(0|0|4 4 0 6.28 1.55 3.14)

### Navigation with the Mouse

3D navigation by Mouse:
· Hold down the left mouse button and move the mouse to rotate the scene.
· Hold down the right mouse button and move the mouse to move the scene camera in 3D space.
· Mouse wheel to zoom in and out.

### Variables for the Input

You can define arbitrary variables in your input (one variable per line). Here are some examples:
· \$x=4 for cuboid, vector, triangle, cube
· \$x=1|2|3 for vector with label
· \$y=2 and \$x=1|2|3 for vector and sphere
· \$x=Test for multiple text usage

• 3D-coordinates of a cube with space diagonal and face diagonal
• Create a straight line with support vector and direction vector
• Plane in space
• Vectors and plane quadrangle
• Plane, vector and line and their intersection point
• Straight lines with track points
• Coordinate planes
• Examples of sphere, cuboid, cube, triangle, vector
• Examples for text rotation
• Example for cuboid rotations
• Create a triangle by 3 vectors, complement a 4th vector for a parallelogramm (3 possibilities)
• Walked way on the surface of a pyramid
• Cone with inscribed rectangular triangle
• Hemisphere
