- Adobe acrobat 3d gratuit free
For example, you can hide and show parts of a 3D model, remove a cover to look inside, and turn parts around as if holding them in your hands. A 3D model initially appears as a two-dimensional preview image. Clicking the 3D model with the Hand or Select tool enables or activates the model, opens the 3D toolbar, and plays any animation. When you open a PDF with 3D content, you see a yellow bar at the top with the message - " 3D content has been disabled.
Enable this features if you trust this document. The 3D toolbar appears after you click the 3D model with the Hand tool. This action activates the 3D model and plays animations that are set to play when the file is enabled. The 3D toolbar always appears in the area above the upper-left corner of the 3D model and cannot be moved. A small arrow appears to the right of the Rotate tool, which you can click to either hide or expand the toolbar.
You can use the 3D toolbar to zoom in and out, rotate, and pan across the object. Use the Model Tree to hide or isolate parts, or make parts transparent. You manipulate a 3D model by selecting and dragging various 3D navigation tools. You can rotate, pan move up, down, or side-to-side , and zoom in or out. Turns 3D objects around relative to the screen. How the objects move depends on the starting view, where you start dragging, and the direction in which you drag.
You can also use the Hand tool to rotate an object. Moves the model vertically and horizontally only. You can also pan with the Hand tool: Ctrl-drag. Moves you toward, or away from, objects in the scene when you drag vertically. You can also zoom with the Hand tool by holding down Shift as you drag.
Pivots horizontally around the scene when you drag horizontally. Moves forward or backward in the scene when you drag vertically; maintains a constant elevation level, regardless of how you drag. The Walk tool is especially useful for architectural 3D models. To change the walking speed, change the default display units in the Preferences 3D.
Navigates through a model while maintaining the surface orientation. Right-click and drag inside the 3D window. The Fly tool moves more slowly the closer you move toward an object. Drag the pointer right or left to turn. To rotate the camera view, click the left mouse button inside the 3D window and drag to turn the camera view.
To return to the starting camera direction, move the mouse back to the initial click point. Use the mouse scroll wheel to move rapidly backward and forward along the camera view direction. This functionality is useful if you get lost within a model or fly into the surface. Camera properties.
Defines the camera angle, alignment, and other properties that define the lens through which a 3D model is viewed. Camera properties are components of views but are set independently. Default View. Returns to a preset zoom, pan, rotation, and projection mode of the 3D model.
Use the Options menu in the View pane of the Model Tree to set a different view as the default. Or use the Manage Views command on the 3D toolbar Views menu to set a different view as the default. If an object ever moves out of your view, you have, in essence, turned your camera away from the object. Click the Default View icon on the 3D toolbar to move the object back into view. Toggle Model Tree. Plays or pauses any JavaScript-enabled animation. Model Render Mode menu. Determines how the 3D shape appears.
For an illustrated guide, see Examples of model rendering modes. Enable Extra Lighting menu. Lists the different lighting effects that are available to enhance the illumination of the 3D object. Experiment to get the visual effects you want. Background Color. Opens the color picker, which you can use to select a different color for the space surrounding the 3D object. Toggle Cross Section.
Shows and hides cross sections of the object. Click the pop-up menu to open the Cross Section Properties dialog box. For more information, see Create cross sections. Enables you to add a sticky note to any part of the 3D model. The note stays with the view. You can also specify a default renderer and determine whether animations are allowed. Enable Playing of 3D Content. The dynamic nature of 3D provides the potential for it to be subject to security vulnerabilities.
Therefore, the auto-play of 3D content in PDFs is disabled by default. Select this option to enable 3D content in PDFs. Preferred Renderer. Depending on your system, you can change your render engine. If Software is selected, rendering takes more time, but the performance is often more consistent with the model rendering of the originating application. Forces the use of a hardware accelerator for even video adapters that do not support a pixel shader.
Enable Double-Sided Rendering. Some model parts have two sides. To save time and space, you can deselect this option to render only the side facing the user.
If the user looks inside a part rendered with only one side, the back side would be invisible. Determines whether the Model Tree is displayed when the 3D model is activated. Default Toolbar State. Determines whether the 3D toolbar is shown or hidden when a 3D model is activated. Lets the user select and highlight parts of the 3D model using the Hand tool.
Selecting this option places the manipulation and navigation tools under the Rotate tool, thereby shortening the 3D toolbar. Enable View Transitions. Some 3D models include animated transitions between views. Deselect this option if you want to prevent this 3D animation. Show 3D Orientation Axis. Turns on or off an in-scene display of an axis that indicates the current orientation of the 3D scene. Optimization Scheme For Low Framerate.
Specifies what happens to animations of complex models when the framerate becomes low. None does not compromise the visuals and leaves the framerate low. Bounding Box shows the three-dimensional planes enclosing the parts instead of the parts themselves, which keeps the framerate high. Drop Objects does not show some parts of the model, which keeps the framerate high. Framerate Threshold. Sets the minimum framerate, either by dragging the slider or entering a number in the value box.
If the framerate drops below that number of frames per second, the Optimization Scheme For Low Framerate option goes into effect. Legal Notices Online Privacy Policy.
User Guide Cancel. Enable playing of 3D content in PDF. Turns a 3D model in parallel to two fixed axes in the 3D model, the x-axis and the z-axis. Measures part sizes and distances in the 3D model. Views menu. Lists any views defined for the current 3D model. Opens and hides the Model Tree. Toggles between displaying perspective and orthographic projection of the 3D object. Specifies the PMI mode to use for rendering. Sign in to your account.
