| + | ====== The New Bezier Patch Tool ====== | ||
| + | |||
| + | {{:mapping:cawe:editingtools:cawe_toolbar_newbezierpatch.png?80 }} | ||
| + | |||
| + | The New Bezier Patch tool is an easy to use tool, if you want to create curved surfaces such as pipes or uneven floors. | ||
| + | |||
| + | A Bezier Patch is in its pure form a plane with a grid of vertices (with variable grid density), that can be moved to change the form of the Bezier Patch. | ||
| + | |||
| + | To activate the tool, use the related icon from the tool bar or press ''SHIFT''+''P''. | ||
| + | |||
| + | ===== The Tool Options Bar ===== | ||
| + | |||
| + | {{:mapping:cawe:editingtools:cawe_tooloptionsbar_newbezierpatch.png}} | ||
| + | |||
| + | The Tool Options Bar lets you choose from different source forms, that a created Bezier Patch will adopt at the beginning. | ||
| + | Possible forms are: | ||
| + | |||
| + | * **Flat**: A simple flat plane. | ||
| + | * **Cylinder**: A Bezier Patch bent into a cylindric form without bottom or top. | ||
| + | * **Open Box**: A rectangular box without bottom or top. | ||
| + | * **Half Cylinder**: A Bezier Patch bent into a half cylinder. | ||
| + | * **Quarter Cylinder**: A Bezier Patch bent into a quarter cylinder. | ||
| + | * **Edge Pipe**: Basic form to easily create edges of pipes. | ||
| + | * **Cone**: A Bezier Patch bent into a simple cone. | ||
| + | * **Sphere**: A Bezier Patch bent into a spherical form. | ||
| + | * **Convex Endcap**: Creates a quarter cylinder convex endcap. | ||
| + | * **Concave Endcap**: Creates a quarter cylinder concave endcap. | ||
| + | |||
| + | The Checkboxes **with convex endcaps** and **with concave endcaps** determine whether a newly created bezier patch should have fitting endcaps at creation. | ||
| + | |||
| + | The fields **width** and **height** define the number of vertices on the two axis of the Bezier Patch. | ||
| + | Higher values mean a higher density of vertices. | ||
| + | |||
| + | Note that these options are not available for all basic bezier patch forms. | ||
| + | |||
| + | The **Subdivs Horz** and **Subdivs Vert** controls adjust the subdivisions of a bezier patch in x or y direction. A higher value means a more seamless bezier patch surface. You can also use these two controls to adjust the subdivisions of a currently selected bezier patch. | ||
| + | |||
| + | Values of -1 mean, that the number of subdivisions is chosen automatically. | ||
| + | |||
| + | ===== Creating a Bezier Patch ===== | ||
| + | |||
| + | {{:mapping:cawe:editingtools:beziercreate.png }} | ||
| + | |||
| + | To create a new patch you have to drag a box in a 2D view that defines the size of the Bezier Patch (note that the box has to be spatial even if you want to create a **Flat** Bezier Patch). | ||
| + | After the box is created you can then resize it to your liking. | ||
| + | Finally press ''ENTER'' to create the Bezier Patch in its chosen source form. | ||
| + | |||
| + | ===== Forming a Bezier Patch ===== | ||
| + | |||
| + | To form a Bezier Patch you have to activate [[mapping:cawe:editingtools:selection]] and select the patch you want to form. | ||
| + | |||
| + | Forming the patch is done by activating [[mapping:cawe:editingtools:morph]]. | ||
| + | Now you can see all control vertices of the Bezier Patch in the 2D views as well as in the 3D view. | ||
| + | You can drag control vertices in both views to form the patch in the same way you drag vertices of brushes (see [[mapping:cawe:editingtools:morph|here]]). | ||
| + | |||
| + | {{:mapping:cawe:editingtools:bezierform3.png}} {{:mapping:cawe:editingtools:bezierform2.png}} {{:mapping:cawe:editingtools:bezierform1.png}} | ||
| + | |||
| + | In this example the center vertice is selected and moved up in a side view. | ||
| + | |||
| + | {{:mapping:cawe:editingtools:bezierform5.png}} {{:mapping:cawe:editingtools:bezierform2.png}} {{:mapping:cawe:editingtools:bezierform4.png}} | ||
| + | |||
| + | {{:mapping:cawe:editingtools:bezierformed.png}} | ||
| + | |||
| + | Altough only the center vertice has been moved, the Bezier Patch has changed its form creating a smooth bump instead of a peak. | ||
| + | |||
| + | ===== Applying materials to Bezier Patches ===== | ||
| + | |||
| + | Materials are applied onto bezier patch surfaces using [[mapping:cawe:editingtools:editfaceprops]]. | ||
| + | |||
| + | |||
| + | ===== New Bezier Patch tool keyboard shortcuts ===== | ||
| + | |||
| + | * ''ESC'' | ||
| + | * Back to Selection tool. | ||
| + | * ''ENTER'' | ||
| + | * If Bezier Box is opened -> create Bezier Patch. | ||
| + | * ''ALT'' | ||
| + | * Temporarily ignore grid snap while creating a Bezier box | ||
