RENDR Dataset

Dataset Description

RENDR is a large-scale synthetic dataset of rendered 3D objects across 11 object categories. The dataset contains rendered images from 3D assets sourced from BlenderKit and Haven, designed for training and evaluating computer vision models on synthetic 3D data.

Normalization Statistics

For standard ImageNet-style normalization:

Mean: [0.5910, 0.5846, 0.5790]
Std: [0.2724, 0.2733, 0.2781]

Usage

from datasets import load_dataset

# Load the dataset
dataset = load_dataset("jneuendorf/rendr")

# Access splits
train_data = dataset['train']
test_data = dataset['test']

# Example: Load with normalization
from torchvision import transforms

transform = transforms.Compose([
    transforms.ToTensor(),
    transforms.Normalize(
        mean=[0.5910, 0.5846, 0.5790],
        std=[0.2724, 0.2733, 0.2781]
    )
])
