View
Here you can enter a name for the view. This will be displayed by the HUD by default.
You can use this setting to change the projection type (e.g., to Perspective, Bird, Diametric).
This box does the same job as the viewport’s Cameras / Use Camera sub-menu — in other words, it allows you to choose which camera the viewport is linked to. Drag & drop the desired camera from the Object Manager into this box.
These settings define the display mode used for active objects.
Gouraud Shading
Gouraud Shading (Lines)
The highest quality display mode for viewports. All objects are shaded with smoothing and light sources are taken into account. The redraw rate is affected most by processor speed and graphics card speed — the faster your CPU and graphics display card, the faster scenes will redraw. If the display update becomes too slow, try reducing the size of the viewport..
In this mode you can add wireframes or isoparms to the Gouraud shading by choosing Wireframe or Isoparms from the
Quick Shading
Quick Shading (Lines)
This is almost identical to Gouraud Shading. The difference is that the auto light is used instead of the scene’s lights to calculate the shading. This can lead to a faster redraw rate.
In this mode you can add wireframes or isoparms to the Quick shading by choosing Wireframe or Isoparms from the
Constant Shading
Constant Shading (Lines)
This option lets you display constant shading only or constant shading in conjunction with the wire frame.
In contrast to Lines mode, hidden lines are not displayed.
The Lines mode allows the complete display of the polygon mesh including hidden lines.
The wireframe mode draws lines on the objects if combined with a mode that allows this such as Gouraud Shading (Lines).
This mode displays isoparm lines for objects that use them such as Generator objects. Other objects such as polygon objects will be displayed in wireframe. This mode will only have an effect if used in combination with a mode that supports it such as Gouraud Shading (Lines).
This mode displays each object as a box. Each box has the same dimensions as the object it represents. Box is the second fastest display mode available, making it useful for extremely demanding scenes.
This is the fastest display mode of all. It is only suitable for hierarchical structures. Each object origin is shown as a small dot and the dots are connected according to the hierarchy. This mode can be useful for character animation. Not only is it extremely fast, it also removes all non-critical lines to expose the skeleton.
Here you can define how the selected Volume Vectors are displayed in the view. For details see Volume Vectors.
To switch off material mapping, disable this option.
Defines whether points, edges or polygons are used for display when the respective surface Normals are oriented away from the camera.
Backface culling hides an object’s elements. If you enable backface culling, you will still see objects behind other objects in wireframe display mode.
If you enable this option, surface Normals will be displayed in the viewport for the selected polygons. Each normal is displayed as a small auxiliary line perpendicular to the polygon’s surface. By convention, the direction of a normal represents the direction of its polygon. In the Options menu you will find a command with which this option can be enabled or disabled.
For example, backface culling checks the direction of each normal to determine whether its surface should be drawn — if the normal points away from the camera, the surface is not drawn (the surface is assumed to point away from the camera, just like its normal).
Disable this option to display all polygon Normals of the selected objects.
Use these settings to define whether or not Vertex Normals should be displayed in Use Point, Edge or Polygon mode (in the Viewport’s Option menu you will find an option for enabling or disabling this feature). When in Use Polygon mode, Selected Only will display Vertex Normals that belong to selected polygons. If this option is disabled, all Vertex Normals will be displayed in all 3 component modes.
As you know, polygon normals are an element of every polygon. A polygon normal is a vector that lies perpendicular to each polygon. Vertex Normals are normals at each of a (non-smoothed) polygon’s points. Each polygon point can have 1 to 4 Vertex Normals, depending on the number of polygons to which it belongs.
These Vertex Normals are evaluated for each visible surface point for shading/rendering and interpolated at this location to produce a soft, homogenous shading.
Currently, displaying surface Normals only serves informational purposes since they cannot be edited comfortably.
You can, however, influence them indirectly, e.g., by applying Use Edge Breaks or modifying the Angle Limit in the Phong tag’s settings:
Left no smoothing, right smoothing via the Phong tag.In the image above, the shading on the left is not smoothed using the Phong tag; on the right smoothing with a Phong Angle of 90°. On the right, are 3 overlapping Vertex Normals. If an interpolation between these three is made for shading, the smoothing as shown, in which the shading edges are removed, will be produced. The result is shading as it would appear on a sphere.
Normal tags that are normally imported with CAD formats, can set by Vertex Normals, independent of surface Normals in order to achieve a better shading (than the automatic procedure described above). By using Normal tags, Vertex Normals can also be displayed numerically in the Structure Manager (
To enter X-Ray mode, enable this option. If the active object is a polygon object, it will become semi-transparent so that you can see all of its points and edges.
Isoline Editing enabled (top) and disabled (bottom).If this option is enabled, all the elements of the Subdivision Surfaces cage object — i.e., its points, edges and polygons — will be projected onto the smoothed Subdivision Surfaces object. This allows you to select these elements directly on the smoothed object. Although it may look like you are selected smoothed parts of the object, you are, in fact selecting cage elements!
A cube deformed by a Bulge object with Deformed Editing disabled (left) and enabled (right).If it frustrates you when you edited a polygon object that is being deformed by a deformer and the polygon object reverts to its non-deformed state as soon as you change to point, edge or polygon mode, now Cinema 4D allows you to edit polygon objects while they are still in the deformed state — simply enable the Deformed Editing option.
Inactive Object
Enable this option if you want the inactive objects to be displayed using different modes to the ones specified on the viewport’s
These settings define the display mode used for inactive objects.
If this option is enabled, the inactive objects will use the display mode defined in their Display tags (if present) instead of the setting defined here in the viewport settings.
Here you can define how non-selected Volume Vectors are displayed at the Viewport level. For details see Volume Vectors.
