To achieve a blur effect on an ImGUI element, you can use an ImGUI add-on library called "ImGuizmo" which provides a variety of additional graphical features, including blurring.
Here's how you can use ImGuizmo to apply a blur effect to an ImGUI element:
Note that you'll need to initialize ImGuizmo before using it, which involves setting up a few things like a shader program and vertex buffer objects. You can find more information on how to do this in the ImGuizmo documentation.
Here's how you can use ImGuizmo to apply a blur effect to an ImGUI element:
- Download the ImGuizmo library: You can download ImGuizmo from the official GitHub repository https://github.com/CedricGuillemet/ImGuizmo
- Include the ImGuizmo header file in your project: Add the following line of code to your C++ source code file: #include "ImGuizmo.h"
- Call the ImGuizmo function to apply a blur effect: Use the ImGuizmo::RenderBlur() function to apply a blur effect to an ImGUI element. The function takes three arguments: the texture ID, the size of the element, and the strength of the blur effect.
C++:
ImGui::Begin("My Window");
// Create a texture ID for the element
GLuint textureID = ...; // Load your texture here
// Get the size of the element
ImVec2 size = ImGui::GetWindowSize();
// Set the strength of the blur effect
float blurStrength = 10.0f;
// Call the ImGuizmo function to render the blurred element
ImGuizmo::RenderBlur(textureID, size, blurStrength);
ImGui::End();Note that you'll need to initialize ImGuizmo before using it, which involves setting up a few things like a shader program and vertex buffer objects. You can find more information on how to do this in the ImGuizmo documentation.
