Tests with painting on glass

[tony]

Thanks Bb:

Simplicity and beauty.

Thanks man!

Is it possible to blend an RGB light with another material using this method?
So you could "etch" a light emitting material onto glass?

Sorry if this is a n00b question. i'm a skindigo person so i like my bread buttered for me!

[BbB]

It should be possible with Indigo 1.1.6.
But it's just me talking out of my XXX since there are no exporters yet and therefore no way for tech idiots like me to test it.
Perhaps one of the XML scribblers, or even the man himself, can enlighten us.

(By the way, why on earth would you want to do this?)

[OnoSendai]

Sure, you could do that in 1.1.6

[BbB]

Man, I'd like to be able to use this baby in the not-too-distant future!

(By the way, why on earth would you want to do this?)

why not! you can do anything these days with synthetic materials n such. from translucent concrete to light emitting paint, architectural materials have progressed a wee bit beyond the ol wood n stone!

a man can dream cant he?

[sugokuGENKI]

i'm trying to emulate video projections onto translucent surfaces (without having to make a complete projector in indigo!)

i'll look into blend with 1.1.6. thanks onosendai! (btw, did you make your eye in indigo? or is that just what happens in the real world when you become master of the realm of the photons?)

[OnoSendai]

The eye is a photo off DeviantArt somewhere

[neo0.]

Im just curious.. The pigm came with an image. WHere do I put it in skindigo? Under the clipmap?

[sugokuGENKI]

so how do I go about setting a material to emit light?
i'd like to blend a light emitting material with a null material using an imagemask.

[sugokuGENKI]

found what i was looking for:

Code: Select all

<material>
		<name>white</name>
		
		<diffuse>
			<colour>0.7 0.7 0.7</colour>
			<base_emission>
				<constant>
					<rgb>
						<rgb>
							2000000000 2000000000 2000000000
						</rgb>
						<gamma>1</gamma>
					</rgb>
				</constant>
			</base_emission>						
		</diffuse>
	</material>

[neo0.]

Can you replace the rose pattern with any other b&w image and it will still work?

[Borgleader]

Why not try?

Here's another etched glass material using BbB's texture:

Code: Select all

	<medium>
		<name>glass</name>

		<precedence>10</precedence>
		<basic>
			<ior>1.5</ior>
			<cauchy_b_coeff>0.0</cauchy_b_coeff>
			<absorption_coefficient_spectrum>
				<uniform>
					<value>0</value>
				</uniform>
			</absorption_coefficient_spectrum>
		</basic>
	</medium>


	<material>
		<name>smooth_glass</name>

		<specular>
			<transparent>true</transparent>
			<internal_medium_name>glass</internal_medium_name>
		</specular>
	</material>

	
	<material>
		<name>frosted_glass</name>

		<glossy_transparent>
			<internal_medium_name>glass</internal_medium_name>

			<exponent>
				<constant>
					30
				</constant>
			</exponent>
		</glossy_transparent>
	</material>


	<material>
		<name>main_mat</name>

		<blend>
			<a_name>frosted_glass</a_name>
			<b_name>smooth_glass</b_name>
			<step_blend>true</step_blend>
			
			<texture>
				<path>blackrose_pattern.jpg</path>
				<exponent>2.2</exponent>
				<uv_set>default</uv_set>
			</texture>

			<blend>
				<texture>
					<texture_index>0</texture_index>
				</texture>
			</blend>
		</blend>
	</material>

.

The glass should really have some absorption.
