If the image contains a lot of subtle details, enable Ramp to make those details easier to see. The following controls are available in the toolbar: Control:Įnables and disables color ramp visualization. In this visualization mode, Unity renders the 3D texture as a translucent cube. The preview image and the buttons on the toolbar change depending on the preview mode. Use the buttons on the right-hand side of the toolbar to choose between Volumetric, Slice, and SDF visualization modes.More info See in Glossary above the preview of the 3D texture. Navigate to the toolbar A row of buttons and basic controls at the top of the Unity Editor that allows you to interact with the Editor in various ways (e.g.The Texture Asset Importer for this Texture Asset is now visible in the Inspector, and Unity renders a preview of the 3D texture at the bottom of the Inspector. In your Project window A window that shows the contents of your Assets folder (Project tab) More info See in Glossary, select the Texture Asset.To preview the 3d texture in the Inspector window: The Handles API lets you configure the preview to your exact requirements, and allows the use of custom gradients. Using the Inspector is quick and convenient, but does not allow the use of custom gradients. More info See in Glossary view using the Handles API. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. Think of each unique Scene file as a unique level. You can preview the 3D texture in the Inspector, or you can write a script to preview it in the Scene A Scene contains the environments and menus of your game. SDF visualization mode renders the texture as a Signed Distance Field in 3D space.Slice visualization mode renders a single slice of each of the three axes of the 3D texture.Volumetric visualization mode renders the 3D texture as a translucent cube.The Unity Editor has three different visualization modes you can use to preview a 3D texture: Save the texture to your Unity ProjectĪssetDatabase.CreateAsset(texture, "Assets/Example3DTexture.asset") Apply the changes to the texture and upload the updated texture to the GPU Y * inverseResolution, z * inverseResolution, 1.0f) Populate the array so that the x, y, and z values of the texture will map to red, blue, and green colorsįloat inverseResolution = 1.0f / (size - 1.0f) Ĭolors = new Color(x * inverseResolution, Create a 3-dimensional array to store color dataĬolor colors = new Color Texture3D texture = new Texture3D(size, size, size, format, false) Create the texture and apply the configuration TextureWrapMode wrapMode = TextureWrapMode.Clamp TextureFormat format = TextureFormat.RGBA32 Public class ExampleEditorScript : MonoBehaviour The following example is an Editor script that creates an instance of the Texture3D class, populates it with color data, and then saves it to your Project as a serialized asset file. Use this class to interact with 3D textures in C# scripts A piece of code that allows you to create your own Components, trigger game events, modify Component properties over time and respond to user input in any way you like. Unity uses the Texture3D class to represent 3D textures. Flipbook image as a 3D shape Creating a 3D texture from a script Set Columns and Rows to the appropriate values for your flipbook texture.įor more information, see Texture import settings.Unity displays the Columns and Rows properties. In the Inspector, set Texture Shape to 3D.Unity displays the Texture import settings in the Inspector A Unity window that displays information about the currently selected GameObject, asset or project settings, allowing you to inspect and edit the values. In your Project view, select the resulting Texture Asset.Import the source texture into your Unity Project.You can import 3D textures from source texture files that are divided into cells. An RGBA32 3D texture with no mipmaps and a resolution of 16 x 16 x 16 has a size of 128KB, but with a resolution of 256 x 256 x 256 it has a size of 512MB. The maximum resolution of a 3D texture is 2048 x 2048 x 2048.īe aware that the size of a 3D texture in memory and on disk increases quickly as its resolution increases. More info See in Glossary, or to store animated textures and blend between them smoothly. Nurbs, Nurms, Subdiv surfaces must be converted to polygons. Unity supports triangulated or Quadrangulated polygon meshes. Meshes make up a large part of your 3D worlds. 3D textures are commonly used to simulate volumetric effects such as fog or smoke, to approximate a volumetric 3D mesh The main graphics primitive of Unity. A 3D texture is a bitmap image that contains information in three dimensions rather than the standard two.
