1. What is the Render Frame Time Calculation?

The render frame time calculation estimates how long it takes to render a single frame based on scene complexity (polygons and lights) and available render power. This helps in planning rendering workloads and resource allocation.

2. How Does the Calculator Work?

The calculator uses the render time equation:

\[ \text{time\_per\_frame} = \frac{\text{polygons} \times \text{lights}}{\text{render\_power}} \]

Where:

\( polygons \) — Number of polygons in the scene (dimensionless)
\( lights \) — Number of light sources in the scene (dimensionless)
\( render\_power \) — Rendering capability of the system (units)

Explanation: The equation shows that render time increases linearly with scene complexity and decreases with higher render power.

3. Importance of Render Time Calculation

Details: Accurate render time estimation is crucial for project planning, resource allocation, and meeting deadlines in animation and visual effects production.

4. Using the Calculator

Tips: Enter the number of polygons, number of lights, and your system's render power. All values must be positive numbers (render power must be greater than zero).

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for render power?
A: Render power should be in consistent units that match your benchmark measurements (e.g., if benchmarked with 1M polygons and 10 lights took 100 seconds, render power would be 100,000 units).

Q2: Does this account for different shader complexities?
A: No, this is a basic calculation. Complex shaders or ray tracing effects will increase actual render times beyond this estimate.

Q3: How accurate is this calculation?
A: It provides a rough estimate. Real-world performance depends on many factors including memory bandwidth, optimization, and specific renderer capabilities.

Q4: Can I use this for animation render time estimation?
A: Yes, multiply the time per frame by your total frame count to estimate total render time for an animation sequence.

Q5: What's a good render power value for my system?
A: Benchmark your system by timing a known scene, then calculate render power = (polygons × lights) / time_taken.
