The history behind holograms

The history of holography commenced in 1947 when physicist Dennis Gabor introduced the theoretical concept, envisioning an improvement for electron microscopy. However, practical application awaited the advent of the laser in 1960, providing the necessary coherent light source for holographic recording. The groundbreaking work of Emmett Leith and Juris Upatnieks in 1962 marked a turning point, leading to the first practical holographic system utilizing lasers.

Throughout the 1960s and 1970s, researchers like Stephen Benton pushed the boundaries, achieving color holography and expanding the technology's potential. Yuri Denisyuk's introduction of reflection holography in 1962 increased practicality by enabling hologram viewing under white light.

The science behind holograms

Holography is a fascinating scientific technique that enables the creation of three-dimensional images through the principles of interference and diffraction. The foundation of holography lies in the coherence of light, specifically laser light, which exhibits a consistent phase relationship among its waves. This coherence is crucial for generating the interference patterns necessary for holographic imaging.

To create a hologram, a laser beam is split into two components: the object beam and the reference beam. The object beam is directed onto the subject, and the light scattered off the object combines with the reference beam. The resulting interference pattern, containing both amplitude and phase information, is recorded on a photosensitive medium such as a holographic plate or film.

Unlike traditional photographs that only capture intensity information, holography preserves the wavefront information of light, allowing for the recreation of a 3D image. When the hologram is later illuminated with a coherent light source, such as the same laser used during recording, the interference pattern is reconstructed. This reconstruction results in the perception of a lifelike 3D image, complete with parallax, enabling viewers to observe the holographic object from different angles.

Holography has found diverse applications, ranging from art and security to data storage and medical imaging. The ability to create realistic 3D images with parallax has made holography an invaluable tool in various fields, continually advancing as technology evolves.

Final Hologram

Creating a hologram was a new challenge for me, and initially, I was uncertain about how to approach it. However, disregarding the bottom part since it won't be included, I don't think it turned out as poorly as I expected. While I'm not particularly thrilled with the result, it surpasses my initial expectations. The hologram lines, in my view, successfully convey the Star Wars reference I aimed for. Additionally, I incorporated subtle details like a small house visible when navigating around the mountain—something I found quite satisfying. Moreover, the inclusion of a few meaningful trees adds a layer of significance to the narrative, contributing to an overall outcome that exceeded my initial apprehensions.

Looking at Logos for fonts

These served as some of the inspirational images guiding the creation of text atop the hologram, aiming to evoke a sense of "Danger" or "Caution." The use of the "Invasion" font, particularly in red, intensifies the feeling of danger, as red is commonly associated with caution. I found the font and spacing of "Prometheius" intriguing, and my goal was to seamlessly blend elements from both "Invasion" and "Prometheius." I believe this fusion was nearly successful, leveraging the font style of "Invasion" and the spacing from "Prometheius."

Taking cues from "Another Earth" and "Alien," I appreciated the effective use of spacing in text. While the font of "Alien" may not inherently convey danger, the color and spacing contribute significantly to capturing the envisioned theme. Overall, I am pleased with how these influences came together in the design, successfully transmitting a sense of caution and danger.

Final Render

Here is the final result of the scene. Overall, I'm quite satisfied with it, though I do think incorporating a few more clouds might have added an extra touch. However, I didn't want to overshadow the prominence of the mountains too much.

[mars2lh-f]

Clouds for a few extra detail

To enhance the scene, I introduced a "sun" light, casting a warm, orange hue that added depth and visual appeal. Despite this improvement, I sensed a need for further detail. To address this, I turned my attention to incorporating clouds using modifiers. Breaking down a mesh into a cloud-like shape, I adjusted the display to "Bounds" to initiate a transparent effect. The chosen orange color persisted to maintain the sunset aesthetic, and the introduction of "volume scatters" enhanced the cloud-like texture. This adjustment brought about a pleasing outcome, and at this point, I felt the scene was nearing its completion.

[mars2lh-f]

Adding textures and details

Upon completing the tree additions, I moved on to incorporating textures into the scene. The first focus was the sky, and I once again employed "geometry nodes" to achieve the desired effect. Introducing the "Mapping" node allowed me to fine-tune the sun's placement, ensuring it peeked through the mountains as intended. Adding color to the trees was the next step, contributing to the overall cohesion of the image. However, upon further review, I sensed a potential excess of trees, prompting me to readjust their quantity in the scene. As I fine-tuned this aspect, I couldn't help but appreciate how the image started to take shape, and I found myself pleased with the emerging result.

[mars2lh-f]

Adding trees

Once I established the foundation for the mountains, I noticed they appeared a bit plain, prompting me to introduce trees into the scene. Learning from a past project where overly detailed trees with particles caused usability issues on various computers, I opted for a different approach. This time, I utilized "geometry nodes" to generate a textured representation of a tree, achieving a semi-realistic look from a distance. It took some time to navigate the process of separating the trees, but ultimately, incorporating a "Random Value" node proved to be the key. This node facilitated a random distribution of trees in different areas while ensuring an even separation.

[mars2lh-f]

Modelling my own mountains

To start shaping my mountain model, I introduced a basic plane into the scene. By applying a series of modifiers, I initiated the process of crafting a textured, uneven surface. Using the "Subdivision Surface" modifier, I began partitioning the mountains into distinct sections. Afterward, I fine-tuned each section, molding them into various shapes to form the layered structure of the mountains. This process proved to be straightforward and didn't demand a significant amount of time to accomplish.

Embarking on the creative journey of crafting the mountainscape, I delved into a contemplative exploration of inspiration resonating within the recesses of my imagination. A crystallized vision began to take shape, one that involved mountains adorned with clouds and, maybe, the gentle radiance of the sun breaking through. Simultaneously, the allure of incorporating the trees showcased in the second photo also is peaking my curiosity.

Choosing to add those trees wasn't just for the aesthetics, it was a deliberate move to make the mountain scene appear more realistic. I want to go beyond a simple picture and bring in a touch of authenticity. Including the trees added a bit of detail and make the whole thing more intricate. My goal is to create something simple but with a realistic vibe, blending elements that capture both simplicity and authenticity. I'm excited about turning this idea into art and confident it will be a harmonious mix of simplicity and lifelike details.
