如何通過界限獲取場景中所有對象的屏幕截圖

Question

我通過vertics數據在Unity3d中生成了一個模型。我創建了BoxCollider，它包含模型的所有遊戲對象。

如何根據模型的邊界（BoxCollider）獲取相機視圖的截圖？

這裏是我的模型

你可以使用這個片段中，我將解釋與評論代碼：

int textureWidth = GameObject.find("UnicGroups").GetComponent<BoxCollider>.size.x; // Width of photo 
int texturHeight = GameObject.find("UnicGroups").GetComponent<BoxCollider>.size.y; // Height of photo 

// You can add EmptyGameObject to your model 
// and move that game object to upper left corner of 
// your model. Then you can replace x and y value 
// with position of that game object 
float x = GameObject.find("UnicGroups/YourEmptyGameObject").transform.Position.x; // x position of upper left corner of screenshot 
float y = GameObject.find("UnicGroups/YourEmptyGameObject").transform.Position.y; // Y position of upper left corner of screenshot 

// create the texture 
Texture2D screenTexture = new Texture2D(textureWidth, texturHeight,TextureFormat.RGB24,true); 
screenTexture.ReadPixels(new Rect(x, y, textureWidth, texturHeight),0,0); 
screenTexture.Apply(); 

// Save image to file 
byte[] dataToSave = screenTexture.EncodeToPNG(); 
// Set destination path for saving file 
string destination = Path.Combine(Application.persistentDataPath,System.DateTime.Now.ToString("yyyy-MM-dd-HHmmss") + ".png"); 
File.WriteAllBytes(destination, dataToSave);
