1.1.1. Feplot interactivity

This tutorial aims at illustrating the main ways to interact with feplot figures.

Step 1 : Initalize feplot with GARTEUR test case

:::{dropdown} Run step . Expand to display source code.

cf=demosdt('DemoGartDataFEM -plot');

::: Run this step to load in a feplot figure the GARTEUR test case. This test case contains a very light FEM model and the computed mode shapes. We will use this test case to illustrate

• camera controls

• shape animation and navigation between shape channels

• images and movies generation

• navigation into the feplot property figure

Note that you can open the list of all interaction with the feplot figure with the key ? when the feplot figure is the current figure

Step 2 : Camera controls

:::{dropdown} Run step . Expand to display source code.

:::

Purpose	Direction	Action / Shortcut
Rotation	Around axis perpendicular to the sight axis and the mouse displacement vector	Ctrl+Drag
	Around u (horizontal axis)	u+Drag u+Scroll u U
	Around v (vertical axis)	v+Drag v+Scroll v V
	Around w (sight axis)	w+Drag w+Scroll w W
Zoom	Along the sight	Ctrl+Scroll a+Drag a+Scroll a A
	To the area in the box	Drag
Translation	Following the mouse displacement	Shift+Drag
	Through u (horizontal axis)	x+Drag x+Scroll x X
	Through v (vertical axis)	y+Drag y+Scroll y Y
	Through w (sight axis)	z+Drag z+Scroll z Z
Default views	(XZ) plane	1
	(XY) plane	2
	"diagonal" view	3
	(YZ) plane	4
ResetView		DoubleClick i
Flip view	From behinds	f

Step 3 : Shape animation + channel navigation

:::{dropdown} Run step . Expand to display source code.

:::

Purpose	Action / Shortcut	Command line
Animation	Shift+Scroll UpArrow DownArrow	fecom anim
Channel	Scroll + - RightArrow LeftArrow Home End	fecom ch+
Deformation scale	l+Scroll l+Drag l L	fecom('Scale')

Step 4 : Feplot capture

:::{dropdown} Run step . Expand to display source code.

:::

Purpose	Action / Shortcut	command line
Capture image		comgui('imwrite',gcf)
Generate movie		fecom('animmovie')

The captured image and movie are shown below : :::{figure} ../_images/TutoFeplotInteract_1.png :width: 50% :name: TutoFeplotInteract_1 ::: :::{figure} ../_images/TutoFeplotInteract_2.gif :width: 50% :name: TutoFeplotInteract_2.gif :::

Step 5 : Interaction with the model / analysis

:::{dropdown} Run step . Expand to display source code.

::: The list below provides the entry points to analyze the model and customize the rendering.

Purpose	Action / Shortcut
Figure menu	File : mainly to save/load data Feplot : rendering options (color, animation type,...)
Context menu	RightClick on the axes background
Node cursor	n
Model properties
