Detailed Description

PerfHud is a plain QtQuick Item (not a 3D node) that you parent into your scene's 2D overlay layer. It reads live rendering metrics from the renderStats of the referenced View3D and shows them in a small dark translucent panel using the Clayground palette.

Metrics shown: frames per second, frame time, CPU sync/prepare/render times, GPU time, draw calls and drawn vertices. Draw-call and vertex counts require extended data collection, which PerfHud enables automatically on the target's renderStats.

Example usage:

import QtQuick
import QtQuick3D
import Clayground.Canvas3D

View3D {
    id: view
    anchors.fill: parent

    PerfHud {
        view3D: view
        extended: false
        anchors.top: parent.top
        anchors.right: parent.right
        anchors.margins: 12
    }
}
