Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.
  • Aalto University students and staff members may print black-and-white prints on the PrintingPoint devices when using the computer with personal Aalto username and password. Color printing is possible using the printer u90203-psc3, which is located near the customer service. Color printing is subject to a charge to Aalto University students and staff members.
  • Other customers can use the printer u90203-psc3. All printing is subject to a charge to non-University members.

Abstract (eng): The problem of the thesis is to create a three-dimensional cave system which can be modified in real time.
The cave system must work fast and look good.

The thesis studies different techniques for creating the cave system.
For example, the marching cubes algorithm is used for creating geometry and triplanar texture mapping is used for mapping textures in arbitrary geometry.
Several methods are also discussed for achieving better graphical quality and efficiency.

The thesis also introduces a prototype as the solution to the problem.
Using the previously studied techniques and some other methods, the prototype is able to create the desired cave system.
The prototype meets the requirements quite well.
The performance and the graphical quality are good.
Surfaces look smooth and the frame rate is steady, even when modifying the land heavily.
Thus, the prototype creates a good base for developing a possible video game in the future.
Abstract (fin): Diplomityön ongelma on luoda kolmiulotteinen luolasto, jota voidaan muokata reaaliajassa.
Luolaston on toimittava nopeasti ja näytettävä hyvältä.

Diplomityössä tutkitaan tekniikoita luolaston luomiseksi.
Muun muassa geometrian luomiseksi käytetään marching cubes algoritmia ja tekstuurien mappaamiseksi mielivaltaiseen geometriaan käytetään triplanar texture mappingia.
Graafisen näyttävyyden ja tehokkuuden aikaan saamiseksi ehdotetaan muutamia tekniikoita.

Thesiksen ongelma pyritään ratkaisemaan kehittämällä prototyyppi.
Käyttämällä edellä tutkittuja tekniikoita sekä muutamaa muuta menetelmää prototyypillä pystytään luomaan halutunlainen luolasto.
Kehitetty prototyyppi täyttää ongelman vaatimukset melko hyvin.
Suorituskyky ja graafinen laatu ovat hyviä.
Pinnat näyttävät sulavilta ja ruudunpäivitys on tasaista jopa silloin, kun maata muokataan raskaasti.
Täten prototyyppi luo hyvän pohjan mahdolliselle pelin kehitykselle.
