Can someone help me with a coding dilemma I'm facing? I'm trying to create a sphere that functions as a source of light, like the sun. I've been experimenting with the meshPhongMaterial options emissive: color and shininess: intensity, but so far I haven't been successful in coding the sun. Does anyone have any tips or suggestions on how to accomplish this? Any help would be greatly appreciated! Thank you!
If you're interested in creating a glow effect, I've put together a variety of examples on my website . You may find these helpful, such as:

Additionally, you can explore more atmospheric glow effects like:
and
I hope you find this information helpful!
The meshPhong material includes parameters for 'emissive' and 'shininess' that impact the calculations within the material shader. However, these parameters will not give you the desired effect as they are solely used for determining the final color output.
If you want to create a glowing sphere effect, one technique is to position a spotlight at the same location as the sphere to illuminate the surrounding objects. Alternatively, you can implement a post-processing shader:
Some examples achieve a glowing effect without post-processing by using a clever trick. They render the sphere and then overlay a quad with a "glow aura" texture in the background. Visit: to see how you can simulate a glow and create a halo-like circle around the sphere.
If you're feeling a little lost without a specific problem to solve, I understand. However, there are a couple key things to consider when trying to make something look like a source of light:
For more advanced techniques, you could also try incorporating godrays.
Best of luck with your project!
