16"aria-hidden="true"><usexlink:href="#svg-link"></use></svg></a> Modes and Actions </h2><p>The basic paradigm in Scotty3D is that there are six different <em>modes</em>, each of which lets you perform certain class of actions. For instance, in <codeclass="language-plaintext highlighter-rouge">Model</code> mode, you can perform actions associated with modeling, such as moving mesh elements and performing global mesh operations. When in <codeclass="language-plaintext highlighter-rouge">Animate</code> mode, you can perform actions associated with animation. Etc. Within a given mode, you can switch between actions by hitting the appropriate key; keyboard commands are listed below for each mode. Note that the input scheme may change depending on the mode. For instance, key commands in <codeclass="language-plaintext highlighter-rouge">Model</code> mode may result in different actions in <codeclass="language-plaintext highlighter-rouge">Render</code> mode.</p><p>The current mode is displayed as the “pressed” button in the menu bar, and available actions are are detailed in the left sidebar. Note that some actions are only available when a model/element/etc. is selected.</p><h2id="global-navigation"><ahref="#global-navigation"class="anchor-heading"aria-labelledby="global-navigation"><svgviewBox="0 0 16 16"aria-hidden="true"><usexlink:href="#svg-link"></use></svg></a> Global Navigation </h2><p>In all modes, you can move the camera around and select scene elements. Information about your selection will be shown in the left sidebar.</p><p>The camera can be manipulated in three ways:</p><ul><li>Rotate: holding shift, left-clicking, and dragging will orbit the camera about the scene. Holding middle click and dragging has the same effect.</li><li>Zoom: using the scroll wheel or scrolling on your trackpad will move the camera towards or away from its center.</li><li>Translate: right-clicking (or using multi-touch on a trackpad, e.g., two-finger click-and-drag) and dragging will move the camera around the scene.</li></ul><h2id="global-preferences"><ahref="#global-preferences"class="anchor-heading"aria-labelledby="global-preferences"><svgviewBox="0 0 16 16"aria-hidden="true"><usexlink:href="#svg-link"></use></svg></a> Global Preferences </h2><p>You can open the preferences window from the edit option in the menu bar.</p><ul><li>Multisampling: this controls how many samples are used for MSAA when rendering scene objects in the Scotty3D interface. If your computer struggles to render complex scenes, try changing this to <codeclass="language-plaintext highlighter-rouge">1</code>.</li></ul><h2id="global-undo"><ahref="#global-undo"class="anchor-heading"aria-labelledby="global-undo"><svgviewBox="0 0 16 16"aria-hidden="true"><usexlink:href="#svg-link"></use></svg></a> Global Undo </h2><p>As is typical, all operations on scene objects, meshes, etc. are un and re-doable using Control/Command-Z to undo and Control/Command-Y to redo. These actions are also available from the <codeclass="language-plaintext highlighter-rouge">Edit</code> option in the menu bar.</p></div></div><divclass="search-overlay"></div></div></body></html>
